The course of the process is monitored by the amount and V, eed of gas liberation. In the R of briquets precalcined at 1100 C, and composed of a mixture of pure quartz sand, charcoal, and sugar (as binder) with 13% excess C, the onset of R was found to occur at 1300-13500 (reaction: SiO?+3C~-SiC+ZCO). As the temperature rises, the reaction SiO2+ C7-Si+ 2C0 begins; max- imum speed is obtained on fusion of the SiO?. The reaction SiO2+ ZSiC = Si + ZCO proceeds at the same time, attaining its maximum speed at the b. p. of SiO2. Parallel with this (start- ing at 13500) there proceeds a side reaction SiOZ+ Si~- ZSiO, with sublimation of the suboxide formed and partial R thereof Card 1/2 in accordance with the reaction SiO+ZC=SiC+CO.

In experiments in R of A1203 from a mixture of the following lo composition: 61.20[o AlZ03, 22.5% charcoal, 16.8016 sugar, (and 556 excess C), the R reaction was found to start at 14000 with a linear increase in rate to 19000 and production of A14C3- From 19500 to 2070-ZlOOO, the reaction rate increases considerably. At these temperatures the reaction A1203 + 3C =2A1 + 3G0 occurs, but the ex- cess AIZ03 converts the Al to AIZO, which is completely sublimated. Metal was obtained in the R products only at Z0700 in a mixture with A14C3 and A1203 (Al yield up to 42016) under conditions of fast heating and short holding. Ye.Z. 1.

Crystallization of titanium on the cathode Is complicated by the 2TiCl3 + Ti I 3TIC12 reaction developing on the surface of forming crystals. The authors investigated the preparation of malts containing TiCl3 and carried out analyses. 'The method described in ReO35 and 6 was employed. The experi- ments were performed in,a medium of purified argon on an installation shown in Figure 1. Results of the experiments are given in a table. The dependence of the current efficiency and the composition of the final electrolyte on the volume current density at 8000C is represented by a set of graphs. It appears that highest current efficiency is obtained if the melt contains 5 to 12% Card 1/~ 80833 S/149/60/000/OY03/009 Investigation Into Processes Occurring on Electrodes In Electrolytic Titanium Refinement TiCl (in g.equ). Higher temperatures cause Increased current efficiency which atas its maximum within the range of 8D00 - 8750C. Further raise of the temperature causes decreased current efficiency. Reactions on the electrodes and the balance of electrode processes were investigated. Values of the de- composition potentials for reactions of reduction and formation of titanium chloride at 8DOOC, calculated by M.V. Kamenetakiy (Ref 12) are given. If the equilibrium electrode potential of Cl is considered as a constant value, the most eleetronegative potential corresponds to the reaction of M24 reduction. This leads to the conclusion cn the consecutive course of anode and cathode reactions. To obtain a satisfactory course of the cathode process, a higher cathode current density is required as well as a relatively high Ti+ oonoen- tration in the melt ensuring the feed of the zone adjacent to the cathode. The reactions on the cathode and anode are Illustrated by Figure 5. The effect of the volume current density was studied in a series of experiments. It was revealed that the amount of TiCl3 and TiC12 contained in the volume of the electrolyte acted as a regulator to maintain a constant composition. As a consequence the part of the current density was revealed, whose optimum value Card 24/3 80833 3/149/60/000/03/03/009 Investigation Into Processes Occurring on Electrodes In Electrolytic Titanium Refinement was 25 - 30 amp/l. It was established that highest current efficiency was ob servedif there was a noticeabl TiC12 concentration in the melt. To ensure a sufficient rate of TiC12 form:tion malts with high activity of TiC13 are recommmided. Beat current efficiency is obtained if the cathode ourritat density is 0.8 - 2.5 amp/cm2 and the anode current density is 0.05 - 0.1 amp/am? at WOO - 8500C.

S/080/61/034/008/'015/018 D204/D305 have been caused by the absence of a method for removing the oxide film, inhibiting stable cohesion between the metal coatings and titanium. Recent work by K.1'.. Batashev (Ref- 3; Naneseniye gallvan- icheskikh pokrytiy na titan iyego splavy (Application of Galvanic Coatings to Titanium and its Alloys), Izd. Doma nauchno-tekhn- prop- agandy, Leningrad, 1959), however, disclosed a new technique for overcoming this difficulty, Before platinum-plating, the surface of the titanium specimens is first processed with emergy paper and washed in carbon tetrachloride, It is then pickled in hot sulphuric acid: the authors recommend a 50'/'*~ solution of acid at a temperature of 60 - 650 for a 10 minute period of pickling. when metal is rem- oved at a rate of not more than 3,,a a minute . Two p1 atinum- plating methods - electrosparking and electrochemical - may be used. In the former process the titanium sample is connected to a negative source of direct current and the platinum wire to the positive termi-aal. elatinum-plating is carried out in an atmosphere of oxygen or argon, and a very fine layer of platinum is formed on the titanium surface. Electrolytic platinization is effected in a solution with the follow- ing composition- 5 - 8 g/1 of Pt as the chloride; 30 - 45 g/l of Card 2,4 S/080/61/034/008/015/018 Platinum-plating,_ D204/D305 (14H4)2HP04-12H20; 200 - 240 g/I of Na2 HP04-12H20, Electrolysis takes place on heating to 600 at acurrent density of 0.1 - I i%/&2. The anode is first platinum and then the platinized titanium; the thickness of the platinum deposit is 0:10 - OA5).1- , when the plat- inum. expenditure amounts to 2 - 3 g/M2 of the titanitua surface. The platinum-plated specimens of titanium were subsequently tried out as insoluble anodes in the electrolysis of sodium chloride and in the electrolysis of water in a solution of sulphuric acid, The tests were continued for 5 - 6 days. and the results showed the absence of any loss in the anodic weight, which indicates good cohesion between the platinum and titanium and the high stability of titanium in such electrolytes Thus, the authors conclude that their data confirm the expediency of the industrial use of titanium instead of graphite, platinum and lead in insoluble anodes, espec- ially in view of the almost negligible consumption of platinum (2 - 3 g/'m2) in -the process of preparing them..

The absorption of hydrogen by titanium was studied in a small nickel. cylinder placed In a tubular oven filled with hydrogen. Saturation of the titanium cathode by hydrogen during electrolysis of sulfuric acid with a lead anode was also tested. In addition, the decomposition of titanium hydride was investigated, and the tests of T. Gibb on r -titanium hydride dissociation tension were repeated. Results showed that the maximum*content of hydrogen In titanium Is 42.96 liters/100 9 of the powder and 38-14 liters/100 9 of the compact and the maxi-: form.

All tests were conducted in ni- trate and chloride melts. A 99. 99% Ag wire served as an anode. The platinum cathode was pickled in concentrated HN03, washed and dried. The kinetics of the nuclei formation on the cathode were determined from the concentration of the Card 1/ 2 L 23836-65 ACCESSION NR: AT4045608 reducible catione, the temperature of the fusion, the surface conditions of the cathode and the current density. The decisive factnr in the formation of crystal- lIzation nuclei is the effect of the surface-active ions in the fused salts. In highly concentrated fusions the rate of nuclei formation is controlled by the -kinetics of a new phase that forms on the cathode surface, the axoms migrating on the cathode surface. In the case of low concentrations, the nuclei formation is conditioned by the kinetics of diffusion both in the fusion and on the cathode sur- face. During the electrolysis of fusions the characteristic constants of the fusing c'nan-p value re--yardless of the degree of cl.)ncentration.

'cate introduces: 1. A method for complex reprocessing of magnesium alloy scrap and waste. -The procedure involves sorting, remelting to istandard alloys', remelting in salt baths, electrolytic,refining and vacuum sublimation. The quality of the resultant magnesium alloys is improved by using a part of the- secondary metal obtained from the salt baths for the charge in smelting standard mag- sium alloys and subjecting a part of this secondary metal to electrolytic refining the three-layer method with subsequent extraction. The anode metal is subjected to vacuum sublimation. 2. A modification of this method in which the vacuum sublimation residue is used as an aluminum-copper base for making aluminum alloys while the conden- isate (magnesium-zinc) is used for making an anode alloy.
