TITLE. Peculiarities of electrodeposition of metals from extremely
pure solutions
PERIODICALt Doklady Akademii nauk SSSR, v. 137, no. 2, 1961, 335-337
TEXT: The authors describe experiments on ~he electrodeposition of the
electronegative metals zinc and manganese from extremely pure solutions.
They found that the chemically pure salts usually used for studying the
kinetics of such processes, do not guarantee the required experimental
purity, not even when they have been recrystallized. Small amounts of
organic impurities in the solution hamper the determination of the influence
of surface-active admixtures on the structure of the cathodic deposit, and
on the value of cathodic polarization. Therefore, the authors used ext-emely
pure ZnSO solutions produced as followss metallic zinc contained lo-5%of
4
admixtures and was produced by sublimation in a nitrogen atmosphere,

following the method of the Gi-pronikell Institute. Chemically pure sulfuric
acid was distilled. Water was boiled in potassium permanganate, and then
distilled three times, but 1/3 (first portions) of the distillate was not
used. The solution thus obtained was boiled again, and then for a long
while exposed to c~irrent from platinum electrodes. By using standard con-
centrations (Zn 60-g/l, H 2s04 100 g11) at 200C,the authors obtained from
this solution a current output of zinc up to 60% at low current density
(1 a/m 2) , and up to 99% at 5 a/m2. Zinc, however, was intensively dissolved
already at 30 a/m2 in an electrolyte of chemically pLu-e ZnSO,, which had been
recrystallized three times. The electrode potential of high-purity zinc
without current or with weak current is shifted by 25-30 mv toward negative
values (as compared to the potential of the conventional LkO(TsO) electrolytic
zinc). Only glass parts can be used in the electrolytic cell when using
high-purity solutions, Plastics (viniplast, organic glass, polyethylene)
change the structure of deposited zinc. Crystals become irregular and
small. On the basis of these results, the authors worked out a method of

measuring the active surface of zinc, which gives well reproducible results,
and is also applicable to other metals (Ref, 5,v- V. 3tender, G. N. Znamen-
skiy, Nauchn. dokl. vyssh. shkoly, ser. khim., 1, 189 (1959)). For similar
experiments with manganese, the authors used an electrolyte of 50 g1l of
manganese (as chloride), and 110 g11 of ammonium chloride. Manganese was
dissolved at pff >1. The solution was purified with manganese sulfide which
was obtained from a previously purified manganese chloride solution and
ammonium sulfide. Ammonium sulfide was obtained by absorption of hydrogen
sulfide by an ammonia solution in water distilled twice. H 2S was obtained
from chemically pure sodium sulfide previously purified from arsenic. After
purification of sulfide, the manganese electrolyte was electrolytically
treated in a glass vessel at a current density of 20-50 a/m2. In the Vessel,
there was an anodic glass cell with a glass diaphragmt a platinum anode,
and a cathode of pure aluminum. The catholyte was constantly stirred.
Anodic gases were sucked off. Munganese hydroxide which was deposited in
the catholyte and oxidized to dioxide by atmospheric oxygen, adsorbed all,
sorts of admixtures from the electrolyte. After filtration, the solution
was subjected to another electrolytic treatment. This process was repeated

three times (a-,together for 200-220 hr). Aluminum hydroxide obtained by
anodic dissolution of A-00 (A-00) aluminum in a pure manganese chloride
solution at a (Airrent cLensity of 10 a/m2' was then added to the solution.
Finally, the solution was filtered with a glass filter. From this solu~
tion the authors deposited manganese at 200C, a pH of "I, and a current
2 2
density of only 10 a/m . At 2000 a/m , the current output of manganese was
9011fa. All manganese deposits were of clear crystalline structure, even
when suspended particles of manganese hydrates were added to the catholyte.
The authors hold the opinion that imperfect crystalline deposits of
manganese, or the absence of deposits at low current densities are due to
admixtures in the electrolyte., The authors found that the crystallization
of zinc and manganese in pure electrolytes does not essentially differ
from the electrocrystallization of silver (A. T. Vagramyan, Ref. 8,
Elektrooeazhdeniye metallov - Electrodeposition of Metals -, Izd.. AIN SSSR,
1950). They state that the kinetics of this process and the action of
admixtures in extremely pure electrolytes should be studied. There are

TITLE: Hydrogen overvoltage on manganese
PBRIODICAL: Zhurnal prikladnoy khimii, v. 35, no.1, 1962, 127-132
TEXT: This work was carried out because of the lack of adequate
information available on the hydrogen overvoltage developing dur-
ing the electrodeposition of Mn from aqueous solutions. The purity
of the electrolyte, used in -the present work, was acceptable on
obeying the following conditions: (a) Mn was deposited on Al at
room temperature at a C. D. of 10 amp/m2; (b) the yield of Mn per
current used at 1000 amp/m2 was 90% and more; (c) Din deposited in
the form of large crystals and was not oxidized in air after dry-
ing. The evolution of hydrogen was investigated in solutions of
(NH 4)2 s04(0.25 N, 1.ON, 3.ON and 5.2 N); Na 23o4 (1 N); and H 2so 4
(0.05 N and 0.1 N). The measurements were conducted in closed., H-
shaped vessel, through which purified hydrogen could be passed;

Hydrogen overvoltage on manganese D258/D304
the direct method of measurement against a thermostatted calomel
electrode was employed. The electrode regions were separated by
means of porous glass diaphragms. A platinqm tablet served as the
anode. This set-up served for measuring the potentials of hydrogen'--
evolution as a function of current density. The plots of the byd.ro.-
gen evolution potential against the log of current density are
shown in Pigs. I and 3. From these and other results it can be
seen that the form of the curves is not influenced by the concpn-..
tration of (NH ) SO , the temperature or by pH. All curves exhibit
at low C. D98 A gudien fall towards the Mn dissolution potential.
The tangent of the straight section of the curve, in the case of
Na2so4 and H2SO4 solutions, is equal to 0.12 and thus near ite
theoretical value. The coefficient a in Tafel's equation is 1.31
at 2500 in the case of hydrogen evolution on Mn in 0,1 N H 2so 4;
its value changes to 1.19 in solutions of (NH 4)2 so4and the cor-
responding tangent changes according to whether the solution is
acidic (.tano(_ -;, 0.16 at pH 6.5) or basic (tanoc = 0.18). The latter

value was determined also for Cd and Zn in bhe same conditions,
thus showing that tano(, depends only on the conditions of electro-
lysis. The temperature coefficient of overvoltage was 1.8 mV/OC
throughout. The more negative evolution potentials in Na 2so4 60-
lutions (as compared wit.i solutions of (NH 4)2 so4are consistent
with the assumption of A. N. Prumkin and coworkers (Ref. 12; "Ki.-
netika elektrodnykh protsessov" (The Kinetics of Electrode Reac.-
tions), MGU, 1952), on the existence of a new discharge mechanism
of hydrogen ions, capable of lowering the hydrogen overvoltage-.

lokova (Ref. 13: Trudy soveshchaniya po elektrol"-.himii, Izd. AN

PERIODICALt Doklady AN SSSR, 1957, Vol- 116, Nr 5, PP. 83B - 840 (USSR)
ABSTRACTs According to modern conceptions glass consists of various domains
which are connected with one another and have no phase separation
limits. A part of these domains consists on the whole of silioa.
In the inner of these domains there are sections with a high degree
of order. The first form the amorphous component, the latter -
the crystallites. Howevort the presence of orystallites in a no-
ticeable quantity is doubted. All experimental proofs of their
existence have one fault: there is no possibaitytD determine quan-
titatively the mentioned components of the glass. In the present
paper the attempt was made to determine beside proving the exist-
ence of the crystallites also their quantitative content in glass.
Final conclusions: 1.) By the investigation of the temperature de-
pendence of the coefficient on Pull it was shown that in the bo-
Card 1/2 rosilicate- and technical glasses polymorphous temperatuietrans-

formations occur. 2.) The binding of the froe silica of the glassets
by matal oxides leads to the vanishing of the polyttiorphous trans-
formations. 3.) One succeeded to fix thermographically the poly-
morphous transformations, however, only in glasses which befors
had been exposed some time to a temperature of from 600 to 700 -
4.) The seyAtivity of the thermal method has turned out to be in-
sufficient for the fixing of polymorphous transformations ill not
prehedted glasses. The inveotigation of the temperUturc deponderice
of the coefficient facilitates to determine their oxi8tence
also in such glasses. There are 3 figures, and 5 references, all

ABSTRACT: Paper presented at the Inter-University Conference
on Dielectrics and Semiconductors, Tomsk, February, 1958.
Poole (Ref 1) and numerous other authors have shown that
the electric conductivity of glass in strong electric
fields does not comply with the Ohm law and from a certain
critical field strength onwards the electric conductivity
increases with increasing field strength according to the
law: aE
Cr = CY0e (1)

Investigation of -the Electric Conductivity of' Glasses in Incensive
Electric Fields
The aim of the work described by the author of this pa*Der
was to establish the temperature dependence of the Pooie
coefficient a and to elucidate the causes of its jump-
like change in the temperature range where polymorphous
transformations of the silica take place. The ej . ents
,~erim
have proved that in presence of a high voltage p arisation
the Poole coefficient oL of glasses is either independent
of the temperature or increases slightly with increasing
temperature. In the temperature ranges which correspond
to the polymorphous transformations of various modifications
of free silica, the coefficient a shows maxima. Thereby,
with decreasing silica content in the glass the magnitudes
of these maxima decrease until complete_ essatiog. From
a certain current intensity onwards, 10 9 to 10-;' A9
the coefficient (x increases relatively sharp y wit
increasing temperature. The magnitude of -the critical
field strength E cr either does not depend on the
temperature at all or decreases with increasinG temperature;

shows a minima. The results of measuring the temperature
dependence of the Poole coefficient oL and of the
potential of the critical field indicate that the glass
contains ordered micro-zones of silica which are
susceptible to polymorphous transformations.

densities. The treatment deals"goth with abrupt and with linear-
gradient p--n junctions. The experimental (curve 1) and
theoretical (curve 2) dependences of the breakdown voltage on the
difference M between donor and acceptor densities are plotted
in Fig. 1 for abrupt p--n junctions In silicon. Both
dependences can be described by .66�0.01
T-n P = kN-0
where k is different for curves 1 and 2. Curve 2 (theoretical)
gave values of the breakdown voltage three times higher than the
experimental ones, because of various simplifying assumptions in
theoretical calculations. The theoretical expressions for the

10 to 30 sec long. It was found that the collector~characteristics
of these triodes are very similar to. those of diodes Ar I LL 22

voltage characteristic and the collector current cbange (4 1) for

voltages not exceeding 0.9 of the breakdown voltage. At higher
reverse voltages, the increase in the current is due to volume

ABSTRACT: The reverse branch of the current-voltage characteristic of IndustrIal
Ge diodes can be subdivided'into 3 sections: (1) a lov-vatage, section where
the reverse current slowly grows with bias; (2) a section corresponding to the
voltages up to 0.9 of the breakdown voltage where the reverse current sharply
increases; (3) an impact-ionization and breakdown section. Reverse
characteristics and collector-qugent increments were measured for various
emitter currents in a p-n-p_Ln.'Moy special Ge transistor. Effect of temperature
on the collector current, for various collector voltages, was %easured within
-160 +22C range; at higher collector voltages, the collector ctirrent passeb

dependence of the inverse current I was investigated in diodes. A
decrease in the inverse current with time is observed in the static
measurements, and the time of establishment of the inverse current
increases with decreasing temperature (T). This is connected with
the filling of the slow surface states, which increases the negative
surface charge and leads to a decrease in the multiplication on the
surface. This also explains why AI is smaller in the static mode
than in the pulsed mode. An investigation of the temperature de-
pendence of I shows that the I (T) curve has a maximum in-'the region,
3 3
of below-zero temperatures, at voltages close to breakdown. The in-
crease in I is attributed to multiplication of the carriers on the
3
-
n junction surface at low temperatures. The reason for the appear_~
p
ance of the maximum on the I (T) curve remains unclear. G. Stepanov.~
