ABSTRACT: In 1955 one of the authore.sucaeaded in developing a simple
method of investigating crystalline dielectrics with respect
to their piezoelectricity (Ref 1) by the mechanical excitation
of piezoelectric oscillations at low frequency near crystal
resonance. The strength of the piezoelectric effect was
determined from the ratio to a quartz standard. Part of the
results of investigations carried out with 1200 crystalline
dielectrics are given by two tables (Table 1: 186 crystals
with smaller piezoelectric effect than quartz; table 2:
111 crystals with a greater effect). It was further found In
Card 1/2 the course of the investigations that a fact of great

importance for the theory or piezoelectrics is the rule
governing the distribution of piezoelectric crystals
according to space groups of symmetry which are favorable to
the piezoelectric effect. This fact may be of use for the
detection of new piezoelectrics among the dielectrics with
known space symmetry. It was further fouhd that the symmetry
assumed in the case of many substances was too high. The
authors thank A. V. Shubnikov for supervising work, and
A. N. Kost, V. M. Belikov and a number of other comrades for
placing the crystal samples at their disposal. There are
2 tables and 9 references, 8 of which are Soviet.

ABSTRACT: The mineral cancrinite is closely related to nepheline
and has the formula (Na 2Ca)4[A'S'0416CO3' (H20) 0-3.
Its hardness is 5-5.5 gnd density 2.42-2.48. The space
group appears to be C 6 = c63 but the piezoelectric
properties agree better with the group 6m . Cry5tal
plates were cut corre--tly oriented to 51 . Dielectric
susceptIbilltles were measured as e 11 622 =-9.5 * 0.1
and c 33 = 11.2 +-0-3 at room temperature with a bridge
circuit working at 50 c.p.s. The loss at 20 kc/s was
tan 6-0-01 and the dielectric strength was about
30 kV/mm. The piezoelectric and elastic constants were

ABSTRACT: Full piezoelectric measurements have been made (by
others) on only some 30 substances. The authors of
this paper have carried out work on the crystallisation
from solution of-materials selected from 120 dielectric
compounds available commercially. Tests for activity
were made on powders. About half the materials tried
could be grown as large crystals from suitable solvents.
7 standard solvents were tried for each. Seeds were
prepared by lowering the temperature of saturated solutions
and were later used in growing big crystals in the
dynamic regime (by crystalliser). A table of 49 materials
is given with certain physico-chemical data and the
recommended solvent. Solubilites are availablo in
standard tables (ex. A. Seidell). Measurements of,the

TEXT: In an earlier paper (Ref. 2), the dielectric constant Ej as well as
the piezoelectric and elastic moduli of cancrinite had been determined at
room temperature. In the present paper, the authors determine its behavior
between +200C and -14000--The temperature was measured with an accuracy
of 0.20C, the dielectric, piezoelectric, and elastic coefficients with an
accuracy of 4, 99 and 3fo, respectively. The same samples were used, that
had served for earlier published determinations. To be true, there occurred
deviations which are explained by the aging in one year. Three different
sections were examined (Pigs, 29 3, and 4). At low temperatures, anomalies
occur in E and the piezoelectric moduli; the precise position is dependent
on the orientation of the cut..The anomalous dielectric behavior of
cancrinite can be explained by the structure (Fig. 1); According to

V. A. Ioffe and I, So Yanchevskayag this anomaly corresponds to a resonance
absorption at 180 kilocyoles; it is possibly the consequence of an electron
transition in the aluminum oxygen tetrahedron from one oxygen atom to an-
other. The piezoelectric anomalies are apparently related to the dielectric
ones, These conclusions are only provisional, an accurate investigation
requires a better structural determination and an investigation on synthetic
material. There are 4 figures and 6 references: 5 Soviet and I Freach.

have the same character in both crystal types. F_ (T), on the contrary,
exhibit considerable differences. The authors also considered temperature
dependences of polarization for different field strengths in the region of
phase transformations of the mentioned crystals. The respective results
are published in a separate article. Fig. 3 shows the temperature depen-
dence of specific heat c p for (NH 4)2SO4* It was found that the cooling
of the specimens at T > T K is not always accompanied by their transition
into the piezoelectric phase. The undercooling was determined as being
about 0.4 4 0-5 0 , which corresponds to dielectric measurement results.
The mean value of integral temperature of transition was 490 cal/mole..The
temperature dependence of c p on (NH 4)2 BeP4is given in Fig. 4. The curve
shows a characteristic X-peak. No undercooling effect was observed. The
discrepancy between the transition temperatures determined calorimetrical-
ly (-J9.9 and -98.60C) and those determined dielectrically (-47.6 and
-93.4 0 is probably to be explained by an inaccurate graduation of the

TEXT: The authors studied the temperature dependences of birefringence

graphic measurements is given in rig. 1. The apparatus was constructed
after blueprints supplied by the designers of the universal microscope
stage (Ref. 6). In the practice, it permits an arbitrarily rapid heating
or coolliig of the specimen and a stabilization of temperature. The
temperature course of birefringence for the c-cut of the (NH 4)2 so4 cry8tal
is shown in Fig. 2. The marked change of the quantity 6 n in the transition
point makes it possible to observe optically the course of the phase

transition in ammonium sulfate crystals. The authors believe that the
coloration of specimenst which proceeds from the corners toward the
center, reflects the transformation process from the paramagnetic phase
into a piezoelectric one. Below the transition point the crystal is cleft
on the plane of cleavage. The authors succeeded in following the
dynamics of this process. At the interface between two phases considerable
inner stresses appear in crystals, the consequence of which is a crystal
cleavage. Fig- 3 shows the temperature dependence of birefringence A n
for the b-cut of (NH 4)2 BeF4crystals in the temperature range from +200 to
-1300C. At -900C birefringence was found to attain a marked maximum.
This can also not be brought in connection with the change of the
geometrical dimensions of the specimens due to thermal expansion. The
domain structure remains invisible even when strong transversal electric
fields are applied. Optical observations confirm the results of dielectric
and calorimetric measurements, according to which there occurs a transi-
tion of first order in ammonium sulfate, and a transition of second order
in ammonium fluoroberyllate, or thereabouts. The present paper was read
at the Third Conference on Piezoelectricity, which took place in Moscow

used in constructing a precision laboratory cryostat for
investigating the electrical and elastic properties of crystals in
the region of polymorphous p~aase conversions. The apparatus was
required to produce stable temperature points every 0.1-0.2 OC;
the stabilization of the temperature should be within � 0.005 OC
for a time of 30 minutes to one hour; the specimens should be
maintained in vacuum or in an atmosphere of dry gas; electrical
terminals in the thermostat chamber should be so designed as to
ensure the complete absence of temperature gradients. The
equipment consists of a cryostat, a temperature stabilising
circuit, a vacuum system and a potentiometer circuit for

temperature measurement. The thermostat chamber of the cryostat
consists of a copper block (9 in Fig.1), 180 mm high and 45 mm in
diameter. In the cylinder are drilled two cylindrical ducts over
three quarters of its length. One duct is used for thermocouples
and the other for ampoules with specimens. The outer surface of
the cylinder is threaded with a four start thread; two of the
grooves contain n1chrome wire heaters and the other two platinum
resistance thermometers. The heater resistance is 1 kilohm and
the thermometer resistance in 300 ohms. Under conditions of
automatic control the surface of the copper block is maintained at
a constant temperature. Because of the good thermal conductivity
of the copper, after an interval of 10-15 minutes the same
temperature is established I.n the volume for the test specimen.
The copper block 9 covered with an aluminium screen 10 Is
placed in a cylindrical glass vessel with double walls. The inner
space is connected to a vacuuin flask containing liquid nitrogen.
The temperature sensitive element is the platinum resistance

thermometer would on the copper block and connected in a balanced
bridge circuit, the other arms of which are manganese resistances
and an inductionless resistance box. When the resistance of the
platinum thermometer alters, it alters the phase of the output
signal from the bridge and the function of the rest of the circuit
is to apply the necessary amount of heat to the heater to maintain
the resistance of the platinum thermometer equal to that of the
resistance box. A schematic diagram of the control system is
given in Fig.2 and the method of operation is explained. The
vacuum system consists of two main parts, one of which is used to
evacuate the inner cylinder of the cryostat and the other to pump
from the glass ampoule with specimen holder. The system includes
a rotary vacuum pump, an oil vapour trap and appropriate valves and
pressure measuring devices. The required temperature in obtained
and maintained as follows. The copper block with.theampoule is
placed in the inner vacuum flask of the cryostat. Liquid nitrogen
is poured into the outer flask in which the level of nitrogen Is

automatically maintained. Cooling commences at a rate of about
0.5 OC/min. When within 3 to 40 of the temperature required to
stabilise,the inner vacuum flask is evacuated until the pressure
in it reaches io-3 mm HS, then the rate of cooling rapidly
diminishes. The bridge is then balanced by means of the resistance
blocks. The automatic temperature control circuit is then
connected and any further reduction in temperature takes place in
steps controlled by the resistance blocks. The accuracy of
stabilisation, was checked by measuring the e.m.f. of a triple
copper constantan thermocouple with a sensitivity of 0.1 mV/oC-
During 60 minutes the temperature changed by less than 0-005 OC.
The cryostat has been working for two years and temperature
characteristics of a number of crystals have been obtained*
Gratitude is expressed to B.N. Vasillyev for useful suggestions and
to A.F. Soloviyev for help in setting up the circuit.

place in piezoelectric crystals without special polar directions
under the action of an electric or mechanical pressures, it
follows that if the crystal is studied in its strained state, extra
piezoelectric and elastic moduli are required to describe its
behaviour. An estimate of the magnitude of the effect is made for

experiments should be carried out to test the relationships

ABSTRACT: The authors carried but precision measurements of the dielectric constant,
polarization, and the coercive field, ~nd also investigaitions of birefrinC,;P_nce of
tetragonal potassium ferrocyanide crystals in the temperature interval -10 - -70C.
The apparatus used for the investigations is described elsewhere (PTE no. 1, 183,
15,051'and earlier). All the electric and optical properties exhibited anomalies near
the ferroelectric phase transition point at -55.6C. For the tetragonal crystals
tested, the irreversible transition is accompanied by spontaneous polarization along
the [1011 and (1011 directions, with values 1 and 0.75 microcoulomb/cm2 respectively.
it was also observed that in crystals with small angler, between the optical axes
irreversible transitions are observed at temperatures that increase with increasing
angle between the optical axes. Comparison of the results with nuclear magnetic res-

onance and other tests made on these crystals leads to the conclusion that a probable
connection exists between the physical properties and the fact that as a rule a
potassium ferrocyanide-cr,/stal does not crystallize with any one distinct structure,
but all its structural types crystallize simultaneously so that it is difficult to
establish the limits governing the crystallization conditions of any particular modi-
fication. Me authors thank G. S. Zhdanav and M. M. Umanskiy for a discussion of
the results. Orig. art. has: 7 figures.

ABSTRACT: The solubility of N14H2PQ4 (AD?) and 041~ZP04 (D-ADF) and the density,
refractive index and conductance of their aqueous solutions were studied in order
to make use of the corresponding concentration and temperature relationshiDs for the
control of the crystallization process. The deuterated compound was prepared by
successive crystallizations of ADF from heavy water. The solubility of ADF and
D-ADF was found to be linearly related to the temperature: o = 26.21 + 0.4463 t, and
the solubility of D-AD? in 1~0 surpasses that of ADP in H20 by about 8%. A plot of
the density of the AD? and D-AD? solutions varsus their concentration gave a linear
dependence. The refractive index data are described by the linear relationships
