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, Card 1/5 S/020/61/137/002/011/020 Peculiarities of electrodeposition... B103/B215 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 Card 2/5 S1020,16111371'00210111020 Peculiarities of electrodeposition... B103/B215 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 Card 3/5 S/020/61/137/002/011/020 Peculiarities of electrodeposition- B103/B215 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 2 figures and 7 references~ 5 Soviet-bloc and 2 non-Soviet-bloc.

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; Card 114e1 !71 frin -:1 S/080/62/035/001/007/013 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 Card 21Y ~ S/080/62/035/001/007/013 Hydrogen overvoltage on mangatieBe D258/D304 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-. BH+ + e--->B + Hads; B + H+ ->BH+ The same explanation is given by V. S. Bagotskiy and I. Ye. Yab- lokova (Ref. 13: Trudy soveshchaniya po elektrol"-.himii, Izd.

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- Polymorphous Transformations of Silica in Silicate Glass 20-5-33A8 formations occur. 2.)

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 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.

It was found that the collector~characteristics of these triodes are very similar to. those of diodes Ar I LL 22 (DG-Ts22).

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.~ 3 DATE ACQ: 10APr64 SUB CODE: PH ENCL: 00 Cdrd 2/2 FREa:OV !.,)f. ) CA';. 1,,~d "V. COG.
