ABSTRACT The phenomenolgioal theory of electrets developed by E.P.Adame
and W.F.G. Swann is here generalized for the case of incrusted el-
ectrets. Incrustation is understood here in the widest sense of the
word, namely as the creation by any means whatsoever of two layers
of charge which are of equal density but which are in opposition to
each other with respect to the sign of the charge on the surface of
the electret. The theory is extended to those electrets which are
obtained from dielectrica, with a specific conductivity that is es-
sentially higher than that of carnauba wax. It is shown that only i
incrustation is taken into account the said theory will lead to
results that are a correct representation of the experimental data
for electreta of carnaubp wax. The theory developed in the paper
is also extended to new electrets produced from aho.rganic dielectri
ca the electric conductivity of which is considerabi.- higher than
that of carnaubs wax. It is shown that the life of eleu,,rets is de-
termined by the quantity I where M essentially depei,-.1s upon
4XV
electret conductivity, its surroundings, and the conditions of :n-
crustation, as well as on the quantity L , where a is a parameter

which characterizes the velocity of the decrease of semiconstant

ABSTRACT It is pointed out that for all hitherto obtained electrets,especial

for the permanent maintenance of the charge was the incrustration
of the surfacel Recently,new electrete have,however,,been produced
from a number of polycrystalline anorgania dielectrica(ppoeramic"

ABSTRACT: The authors were the first to demonstrate that the stable
electrets, the properties of which are not connected with
Seignette-Electricity, can be determined from polyoristalline
anorganic compounds as e.g. the titanates of magnesium, calcium,
bismuth, strontium, zinc, strontium-bismuth-titanate, the barium
metatitanate, barium teratitanate and also steatite. The elec-
trets are in all cases produced by the following method: The
sample was placed in an electric field of 20 kV/cm where it was
left at room temperature for 30 minutes; it was then heated to
200* C for two hours and kept at this tem 9erature for two hours,
the temperature was then reduced to 65-90 C for two hours. The
samples were of 5 mm thickness, their diameter was - 60 mm.
The electrodes consisted of brass disks with a diameter of
30.0 mm. The surfaces of the samples and of the electrodes were
carefully polished. Amperage was measured during polarization.
By the method of electrostatic induction a certain effective

surface charge density a of the electrets was measured and the
signs of the charges were measured on the surfaces of the
electrets.
The most important results are shown in a table. The signs of
the charges at the end of the samples examihed agree with the
signs of the voltage which was applied to the samples during
polarization. Only in samples of Pyrex-glass did the aharges
have opposite polarization. A diagram illustrates the time
dependence of a for an electret of CaTiO . A similar time de-
pendence also applies in the case Of Othir electrets. According
to preliminary experiments with samples of MgTiO3 the life of
these eleetrets is more than 1,5 years.
According to the data found here the surface density of the
charges of the new electret in all cases attains the corres-
ponding values of the electret of carnauba. wax
(1-2.10-9 coul/cm2). In some cases these values are consider-
ably exceeded. It is a characteristic fact that the dielectric
receives homogeneous charges also with polarizations without
heating. These charges, however, gradually decrease much more
rapidly than those charges obtained in the case of additional

smaller one month after polarization than the corresponding
value of a obtained when heating the samples to 2000 C.
The investigations discussed here are continued.

ABSTRACT: More than 60 different dielectrioe - mainly organic
substances - were investigated with respect to the possibility
of obtaining electrets (refs. 1- to 6). Electrets from in-
organic Pol crystalline dielectrics (the socalled ceramic
dielectrics~ without piezoelectric properties were not yet
obtained. The authors tried to obtain such electrets from in-
organic dielectrics which do not contain any polar groups,
and to investigate their properties. They investigated poly-
crystalline dielectrics with different dielectric constants:
Titanates of magnesium, of calcium, strontium, bismuth, and
strontium-bismuth-titanates, barium-metatitanate and
barium-tetratitanate, steatite and porcelain (of the brand
M-23). Individual solid, amorphous and monocrystalline
Card 1/ 4 dielectrics were investigated besides these polycrystalline

materials. Table I shows a brief characteristic of these
materials. A certain effective density of the surface-charge
a was measured after the polarization of the sample on its
surface. As a rule, the charges on different surfaces showed
no essential differences with respect to the quantity of
charge. The results of measurement of d are only given for
the negative side of the electrets. The negative sign of 0
corresponds to the homogeneous charge, the positive to the
heterogeneous charge. Homogeneous charges are obtained with
all materials (table 2). It is evident that under corresponding
conditions not all investigated substances become electrets
after polarization (tables 2 and 3). a changes abruptly
according to time with decreasing tendency (fig. 1). The
abrupt character of the curve is apparently correlated with
the change of the surrounding temperature and humidity and
the reduction of a is apparently correlated with the repeated
measurements (figures 5 to 10)- It results from the current
measurements with the polarization of the other not given
dielectrics as well as from (fig. 11) that any anomalies are
not observed on the curve of current change according to time
Card 2/ 4 and temperature. The second part of the work was devoted to

the determination of optimum conditions with the polarization
of newly obtained electrets. A certain dependence on the
temperature constancy is observed which changes its character
according to time (fig- 13). 2000C is apparently the optimum
temperature for these dielectrics. 3000C represent a limiting
temperature, since at a higher temperature either a thermal
breakdown at E - 10 -' 20 kV cm-1 takes place, or chemical
change of the materiai correlated with the increase in con-
ductivity. It was essential to find out how the amount of the
density of the surface-charge changes according to the tension
of the voltage of the applied field. (Figures 14 and 15). As
results from the diagram (fig .16), no essential dependence
of the electret on the applied voltage with E - const was
determined. A series of samples was polarized at room-tempera-
ture in order to determine the role of heating with the ob-
taining of electrets. The obtaining of inorganic electrets by
means of intermittent voltage is also achieved. The properties
of the electrets obtained in this way do almost not differ at
all from the electrets obtained with direct voltage. The
Card 3/4 hypothesis developed by Gross was also examined (ref. 10). The

results obtained show that the formation of homogeneous
charges is substantially more complicated than Gross
assumed. It was shown previously (refs. 11 and 12) that both
homogeneous chargee and heterogeneous charges are space
charges. The authors tried to confirm this on new electrets.
They also measured & and tg 6 of CaTiO and SrT'O and
compared the obtained values with Thos. of the cohrol-
-samples. Almost no change of the,6 of the electrets was found.

ABSTRACT: The authors review methods and equipment used in measure-
me.nt of the surface charge of electrets. The review begins
with a description of the electric field of an electret be-
tween two metal electrodes at the same potential (the "short-
circuited electret"7 Fig 1). Gubkin (Ref 6) showed that the
electric fields between the electret surfaces and the metal
electrodes and the field inside an electret are given by

m-th surface of the electret. Three methods of measuring
the electret surface charge are discussed in the present
review. One of these methods is the electrostatic induct-

is in contact with the upper electret surface with the switch
K closed. It follows then from Eq (1) that if

means of an experimental electret vibroprobe made of a calcium

fixed into a special insulator base C. The membrane E is above

the electret surface, the air gap between the membrane and the
electret surface was 0.015 cm. A thin brass foil was used as a
second electrode. The membrane was connected to the metallic
body A which was grounded; from the second electrode a lead D
to the external circuit was provided. The surface density of the
electret charge equalled 2 x 10-9 Coulomb/cm 2. The signal was fed
to the input resistance of a tube voltmeter with R = 2 megohm.
The experimentally determined resonance frequency of the mobile
electrode f equalled 1650 c.p.s. Good agreement between
calculated ana experimental results were obtained. Fig.3 shows
the sensitivity of the vibroprobe with respect to acceleration N
(mV/g) as a function of the vibration frequency (C.P.S.). It is y
pointed out that electret vibroprobes operate without external
supply sources and, in contrast to electromagnetic probes, the
alternating current is induced by the electric field and not by the
magnetic field. rf the system, electret system-mobtle electrode,
is considered as a plane condenser, a certain analogy can be
arrived at between electrets and capacitance probes, the main
difference being that capacitance probes require an external field.

TEXT: This is a short review of publications on electret research; only
such electrets are studied as consist of polycrystalline inorganic
(ceramic) dielectrics. In the introduction, the first papers published
in the twenties and thirties are briefly dealt with, and the production
of electrets (thermoelectrets, photoelectrets, electroelectrets -
according to the production method) is discussed. The occurrence of a
charge or a field in the electret is described, and formulas are given.
Charge measurement (electrostatic induction, depolarization) is also
mentioned, and the two methods are briefly discussed. The dependence of
the surface-charge density (O,ff)of electrets on external effects is dealt
with in the following (deff between 10-11 and 10-8coul/OM2; residual

represented and discussed. The dependence Of deff on air pressure W ~V/
corresponds to the Paschen curve for a gas discharge in a homogeneous
field. A table (taken from Ref. 11) gives the residual polarizations P
of a number of ceramic electrets, which had been polarized at room
temperature and 2000C in fields of 2 and 20 kv/cm. 6 denotes the piezo-
modulus; $(1) is a strontium-bismuth titanate (specimen No. 7). Today
it is assumed that electrets have both homo- and hetero-chargee, and
that they usually have surface and volume charges which may be both bound
and free. In the following, aeff of various electrets is studied as a
function of the E-field and of time, and some formulas are given. Next,
the piezoeffect is dealt with; Ref. 11 showed that 1) the quasi-piezo-
effect (at dP/dp = O)islO-Ilooul/kg on the average, and that 2) the
piezomodulus of Sr-Bi titanates is 1-5*10-11 coul/kg (p denotes
mechanical pressure). F~riher, papers by Gross et al. (Phys.Rev.) are
briefly dealt with, the molecular and phenomenological theory of the
electret effect is discussed, the latter in detail (acc. to Gubkin,

TITLE: Investigation of the dielectric properties of strontium
bismuth titanates at low temperatures
PERIODICAL. Fizika tverdogo tela, v. 3, no. 4, 1961,11io-1116
TEXT: The present work is a continuation of a series of investigations
of the dielectric properties of strontium bismuth titanates (SBT).
The SBT have a high dielectric constant and show a very strongly marked
relaxation polarization. SBT have no ferroelectric properties - the
high iE-value is related, howeverv with the relaxative character of
polarization. In order to determine accurately the character of polariza-
tion in SBTI a large number of different kinds of experiments are required.
The present paper makes a contribution to this by investigating the fre-
quenoy and temperature dependence of Eand tan ~, as well as the dielectric
hysteresis in SrTiO 3 - Bi 203-3T1020 The composition (in mole%)-and the

sintering temperature of the 15 samples studied are given in the table.
The results of the investigations are illustrated in diagrams. It is
seen that all pastes with a bismuth titanate content of more than 0.1 mole%
(at 1 kc/sec) have one maximum of ~_ that is sMfted toward higher
temperatures with increasing bismuth titanate content (pastes 2-9).
Pure SrTiO3 (paste 1) shows the highest value (-~ z 6300) at T < -196"c.
The temperature dependence of tan 6 (at 1 kc/sec) shows two maxima. The
first lies at about -2500C, is low for pastes 1 and 2, and highest for
paste 4, higher than the second (which is a special case)~ Its intensity
again decreases rapidly; for paste 9 it is most indistinct. Its
position remains unchanged. The second maximum increases throughout in
intensity and width; however, it is shifted rapidly toward higher
temperatures. The curves ;(T) and tan i . f(T ') are seen to be practically
independent of frequency for paste 1. It is seen Dirther that the
low-temperature maximum relative to its position is independent not only
of the composition but largely also of frequency. The second maximum is
shifted toward higher temperatures, and with increasing frequency it
decreases in intensity for E and increases for tan 6. Pigs~ 6, 7, and 8

show the corresponding curves for pastes 99 12, and 15, respectively.
All pastes showed hysteresis loops at, low temperatures, but not at room
temperatures (at least up to field strengths of 50-60 kv/cm). At the
temperature of N, the saturation is hardly marked. Pure BaTiO 39 by
contrastf shows saturation at He temperature, and that already at 3-kv/cm;
at 10 kv/cm, it is very clearly marked. The results obtained can be
explained from two points of view: 1) on the basis of relaxation
polarization due to structural defects, and 2) on the assumption of
spontaneous polarization. In this case, the relaxation phenomena are
related to the domain mobility. Further investigations should clarify
finally the problem of the nature of polarization. There are 10 figures,
1 table, and 4 Soviet-bloc references. '

TITLE: The physical nature of the electret effect in Brazilian wax
PERIODICAL: Fizika tverdogo tela, V--4,J19-'5, 1962, 1196-1205',i,
T EXT :The electret effect in Brazilian wax is due to remanent polarization.
After polarization in a powerful electric field (field strength 1.5-15 kv/c )
M)
at elevated temperature (20-700C) the electric field was turned off and the
discharge current I measured. When the discharge current had dropped to:
dis
zero, the specimen was heated and the depolarization current I dep deter-
mining the remanent polarization was measured. The remanent polarization,
which varies very slowly, increases from 1-10-10 to 5-10-8 coulomb/OM2
with Dolarization temperature and electric field strength. Charges
qpposite~ to those of polarization may reach the surface of the electret by
spark-over in the air between the electret and the electrodes or in a
similar way. 7then the external field is switched off, the free charges
of the dielectric are shifted in the internal field of the electret. The

total charge of the electret changes signs a few minutes after its
preparation, reaches a maximum, and then remains virtually constant.
Dooolari,zation is the same both with electrets stored for a long time and
with ""reshly prepared specimens. Owing to the non-zero relaxation time of
free charges, the free charges lag behind the change in remanent polariza-
tion. The delay determines the stable charge 6 - T P/-r of-the ferroelecti-A
where i is the relaxation time of remanent polarization, and i M is that of
the free charge. The formula

for the time required for the electret charge to pass through zero (a 0)

TEM Earlier work (FTT, 2, 12, 3077, 1960; 3, 4, 1110, 1961) in studying-
the nonlinear properties of the system SrTiO 3- Bi203' MO2 is continued.
The specimens had relaxation properties. The'maxima of the E and tan
versus temperature curves are shifted to higher temperatures when the
frequency of the field applied is increased. The dependences of.C and
tan S on thb field strength, and the hysteresis loop, both have the same
characteristics as those of ferroelectrics, but the characteristic jumps
ol: 6 associated with phase transitions do not occur. This fact supports
the suggestion that the nonlinear properties may be caused by relaxation
polarization, but low-temperature minima of the coefficient of linear
expansion are indicative of phase transitions from the paraelectric into

ABSTRACT: The dielectric constants and dielectrIc losses of D'20 eft"O cempoixids'With

and frequencies from 50 to- 1. 1 x 106 cycle/see In both strong ~ and weak f ields. The
results obtained for B120 t3T102 are presented graphically and discussed. The mater-
ial was synthesized at 148;o and consisted of a crystalline phase with a very small
admixture of vitreous material. The material was found to be a Iferroelectric with a
diffuse phase transition in the vicinity of liquid nitrogen temperature and to behave
at higher temperatures like a typical relaxation dielectric, exhibiting relaxation
polarization. Hysteresis loops could be observed only at liquid helium temperatures.

The dielectric. constant maximum in the transition region was -very broad and did no:t
shift with changing frequency. The loss tangent showed two small maxima in or., near the
transition region and a maximum at a higher temperature, which was-very pronounced and
occurred at about 3200K for a frequency of 5 kilocycle/see. The near room temperature
maximum of the loss tangent varied considerably in magnitude and temperature with
changing frequency; at 1.1 megacycle/see this maximum was barely perceptible, the
room temperature loss tangent and dielectric constant being approximately 0.025 and
2.00, respectively. At 800 kilocycle/sec and 293% the reversible dielectric constant
decreased by less than 20% when the bias was Increased from maro to 100 W/ca.~ It In
concluded that dielectrics exist in which ferroelectric and relaxation properties are
closely associated. Orig, art. has: 5 figures.

ABSTRACT: To check on the anomalous behavior observed in bismuth titanate by many
investigators and to reconcile some of the discrepancies between their results, the
authors have tested polycrystalline bismuth titanate obtained under controlled con-
ditions. The frequency dependence of -the dielectric constant and of the loss angle
were characterized by a decrease of the dielectric constant with increasing frequency
and by a maximum of the loss angle. The dielectric constant decreased from 350 at
about 100 cps to 240 at 109_ 106 cps, while the loss w1le tangent had a max1mum of
0.14 near l03 In
cps and then decreased to 0.01 at 105 - 10 cps. The temperature de-
pendence of the dielectric constant exhibited a maximum near 100K at all frequencies.
At high temperatures (500K) there was a pronounced frequency dependence, characterize
by a rapid rise of the dielectric constant with temperature, especially &t frequen-

cies near 10M cps. Electric hysteresis loops were observed only at liquid-nitrogen
or liquid-helium temperatures. The testa results are analyzed and it is concluded
that bismuth titanate is ferroelectric at temperatures below liquid ii1trogen and hag
relaxation properties at higher temperatures. A hypothesis is advanced that the
ferroelectric properties are possessed by the entire series of bismuth titanate
M203*n=~! with different values of n, and that the forroelectric propeities of
these and similar materials are closely related with relaxation properties. Otig.

tude of the wave, ~as can be found from the equations of hydrodyn~n-.iics. The same
difference also is encountered in the speed of.the shock front in comparison with
the speed of propagation of the perturbations. Tim's a nonlinear distortion oi the
-wave occurs. The points of the wave profile with great amplitude move with a
greater speed than those points of the profile in which the deviations from the Un-
perturbed, state: are smaller. Thus,. linear thaory supplies valuOti that ara, V&Iid for
the small- per turbati on points, but a distortion occurs that.grow~ with time. Thus,
~.Iinear theorIy is in effect limited to short time periods only. Upon propagation 'of
waves over great distances the nonlinear effects lead to the formation of discontinu-
ities in the. sound waves (if their' ihitial form was continuous), and to a supplam,~n-
tary change in.the amplitude of the shock front as compared with that obtained by
linear acoustics. The resulting changes in amplitude are eXplored theoretically,
and the results obtained are employed for the calculation of; the Amplitude, impose,

ABSTRACT: Tick encephalitis has been invostigr~foi for ?C yoarn. Tt 13
an acute infectuous disease which c[Minly th,! central
nervous system.,and often results in disability %nd even in
death. The tick encephalitis virva is transinitted to man ma:Ln_ll
by pasturing animals. The incubation period is 7 to 21 clays.
tfter hibernation the ticks first appear in mid-April or
mid'-.Alay (Primorlye or high-mountain Taiga in tho Sovi-~t Par
East). They are most active in the mornings in.: ~2venin '--3. The
majority of infectione in men occur in May to J,,in-:!. In the
paper tinder consideration measures for the prcvention of the
infection are indicated. The first measures were
scientifically founded and developed in the U337? by Ye. 'i.

the skin and bf how to remove the tick. It is recommended
to soak clothes in dimethyl ah-1--halate, a procedure to be
repeated every 5-7 days. For first aid, the medicine chest
by Profesdor A. N. Shapoval is recommended. Animals, grass,
and shrubs are to be'treated with DDT and hexachlorane. -
Team Nr 217 of the Dallnevostochnoyo AGP (Soviet Far East
Aerogeodetic Enterprise) in 1956 took all measures for the
control of the infection, and have succeeded in completely
preventing the occurrence of tick encephalitis. The
individual measures are indicated. There are A Sovict

PERIODICAL: Grazhdanskaya aviatsiya, 1958, Nr 2. pp 19-21 (USSR)
ABSTRACT: The artiole Is a report on the results of noise level
tests carried out in the State Scientific Research In-
stitute with the Tu-104 jet and the Il-14 conventional
airliners. The results of tests are compared with each
other and with those of the French Caravelle jet air-
craft. The conclusion is that the Tu-104, flying at
375 m. altitude and rated engine speed creates a noise
level at a listening station placed 4 0500 m. from the
take-off point equal to that of the 1,-14 plane passing
at an altitude of 200 m, The noise level of the Tu-104
