The velocity of the dissolution of steel IC~22T depends on the potential in rather a complicated way. The behavior of steel at different potentials is described in short. The minimum velocity of steel dissolution is within the potential range of from 0 to 0,500 V. Also the other types of steel investigated Card 1/3 showed similar dependence of dissolution velocity on the The Influence of Nickel Upon the Electrochemical and SOV/2o-120-4-43/67 Corrosion Behavior of Steel potential. The addition of nickel decreases the dissolution velocity in all potentials that are more negative than + 1,200 V. The velocity of dissolution systematically decreases within the range of passivation in the case of an increase of the nickel percentage in steel. The addition of nickel has almost no in- fluence upon the position of the curve which characterizes the over voltage of hydrogen. To convert steel into the passive state and thus also to increase its resistance to corrosion the stationary potential in the case of absent external polarization must be shifted towards the positi-ve side, up to values which are more passive than the passivation potential. Such a shift can be brought about by the increase-of the over voltage of the anodic reaction and also by increase of the total velocity of the depolarizing cathodic reactions. The authors decreased the over valtage of hydrogen by facing a small quantity of platinum upon the steel surface. Simi-lar results were obtained by intro- ducing atmospheric oxygen into the solution. The degree of passivation of the surface of a steel with given composition is a function of the potential and in the cases described does Card 2/3 not depend on the method of maintaining this potential. A shift The Influence of Nickel Upon the Electrochemical and SOV/2o-12o-4-43/67 Corrosion Behavior of Steel of the potential by a change in the chemical composition of the steel can considerably change the degree of its passivation with a given potential. In conclusion, the authors thank A.A.Babakov for having placed the steel samples at their disposal. There are I figure, 1 table, and 4 references, 3 of which are Soviet.

There are two basic superstructures and an indefinite number of derivatives, In each case layers are built out of cubo-octahedra, for cubic close packing (c.,c,p.) these layers are plane and for the hexagonal close packing (h.c,p,) or mixed arrangements they are pleated. The second layer- built up like the first, can lie over the holes between the cubo-octahedra of t~e preceding layer (first type, denoted KK) or over the square sections of the cubo--octahedra (second type, denoted KKI). Derivative structures are obtained by alternating these layers.

Sometimes the displace- ments are ~3o large that one can hardly talk of close packing (Na,,AIF etc..). In the KK type, octahedra, - 6 fill-ing the spaces between the cubo-octahedra, lie at the points of a primitive lattice. Their centres form a simple cubic structure, These octahedra are fully partially oGcupied by other atoms, Each atom M is surrounded by an octahedron of Q atoms and each Q by 2,3,L~,'~ or 6 atcms of M. For the composition Mq the structure NaC.1 seems the only possibility. For MQ-2 there is also only one possible packing system, Stru~~tur(-.-s arei listed with cubic ~;iose packing ABC, h.c.p. ~B,, ABAC.

References are given for those not appearing in Structure Reports (UP to Vol 13)~ It is concluded that: 1) The superstructures in both intermetallic and inorganic compounds where there are the same types of arrangements are identical. 2) Tables of the possible superstructures are useful as an aid to determining structures by trial and error. 3) Superstructures have a more general applicability than coordination polyhedra but not as general as structure types. 4) There is a series of simple variants in the arrange- ments of atoms in the sites of exact close packing and very many structures can be described in such terms.

TITLE: Possible Disposition of Atoms in the Octahedral Spaces of a Close-Packed Hexagonal Structure PERIODICAL: Kristallografiya, 1959, Vol 4, Nr 5, PP 778-782 (USSR) ABSTRACT: Let each of the X atoms that form a close-packed hexagonal structure be equally surrounded by A and B atoms, placed in the octahedral spaces of the structure. Thereby, A or B may mean an atom or a lattice vacancy.. In any event, any X atom is, then, confined to the body center of a rhombohedral prism, whose vertices can be occupied by A and B in rational proportions such as 1:5, 2:4, 3:3. These ratios will lead to the compounde of AB, X6 or A5BX6 AB 2X3 or A2BX 3j and ABX2 types respectively. At the came time, A and B can be conaidored to form thoir own atructuroa interpenetrating one another, In the case oV 1:5 ratio, the hoxagonalk prisms, formed by B, Card 1/3 will have A at the body contor*, but tho prio= may join Possible Disposition o' Atoms in the Octa- '1600", hedral Spaceb of a Clo!3a-PackQd ifaxaGonal sov/7c-',,-5-26/36 Structure Card 2/3 cach othor along the prism face with 0 or I unit transla- tion. Thuu, two different s1Cructurou will emerge. if the ratio is 2:4, A may occur along a prism edge, basal edge, or face diagonal of the rhombohedral prism. Con- sidering the interpenetrating A and B StrUCtUrcs, 7 possible combinations are found to lead to the three different dispouitions of A; in other words, 7 struc- tures may be formed. If the ratio is 3:3, the 3 A (or B) atoms may be confined to a basal face, prism face, or to 2 different prism faces. Here again, a number of possible combinations of the interpenetrating A and B structures may lead to the three kinds of A distribution. Thus, ABX 2- type compounds may occur in a number of structural varieties. The discv- . -,ibina- tions are not the only possible combi.nations, since the A:B ratio may vary from one rhombohedral prism to the next.

TITLE: Production of Pure Xenon (Polucheniye chisto-o ksenona) CD PERIODICAL: Pribory i tekhnika eksperimenta, 1959, Nr 11 p 149 (USSR) ABSTRACT: A method of separating the hydrocarbons present in xenon is described. The elimination of the hydrocarbons was done by employing a highly active reagent which is prepared by depositing a layer of copper oxide on a surface of silica .-el. The reagent was placed in a short quartz tube (havin- a lefigth of a few cm), and dehydrated at a temperature of 3000C. The tube was then heated to ?OOOC, and the xenon to be purified was passed through it. The device operated as a chromatographic column in that the change of colour of the reagent after the reaction permitted the observation of the front forming in the column. A preliminary filling of the column by xenon was done very slowly. Subsequently, the xenqn was passed in a continuous stream, at a rate of about 1OVemchr, through the heated column and through another two coltuans operating at the ambient temperature. The other two coliimns captured the carbonic acid and the water vapours which formed durin-- the oxidation of the hydrocarbons. ifter the operat- ion the column was regenerated at 6000C. By the above method Card 1/2 it was possible to obtain a spectrally pure xenon; the lines SOV/120-59-1-44/50 Production of Pure Xenon of hydrogen and oxygen could not be detected, nor were the molecular spectra of hydrocarbons present. The method can be used for the purification of other rare gases. The authors express their gratitude to N. A. Teterina for carrying out the spectral analysis.

TITLE: Application of ion-exchange membranes in the hydrometallurgy of uranium PERIODICAL: Atamnaya energiya, v. 10, no. A, 1961, 353-361 TEXT: Since large amounts of acids and alkaline solutions are consumed in standard Drocesses of uranium sorption and extraction, the authors have applied electrodialysis with ion-exchange membranes for neutralization of acid or alkaline uranium solutions. This method has also been successfully applied to reduce U VI (from hydrochloric solutions of borate having up to 300 g1l of uranium) electrochemically to U IV. Such ion-exchange membranes (ionitemembranes) promote either anion or cation diffusion (anionites, cationites). The membranes the authors have been delivered from the Nauchno-issledovatellskiy institut plastmass Goskomiteta po khimii (scien- tific Research Institute of Plastics of the State Committee for Chemistry) and the Moskovskiy khimiko-tekhnologicheskiy institut im.

First, the application of ion-exchange membranes is described, which are used to remove excessive acid in uranium solutions. The membranes have been tested with sulfuric, nitric, and hydrochloric solutions of uranium. Two-, three-, and twenty-chamber electrodialy~ers made of organic glass and having a capacity of 30-1500 ml were used for the purpose. Platinum, tantalum, graphite, lea4 and stainless steel served as material for electrodes. Wori.- with two- chamber electrodialyzurs. The following setup has been used to remove excessive acid from sulfate solut4- having different uranium concentra- tions: H2so4 UO so 2 4 2- H H 2so4 SO4 FU02 (SO4)nl( 2~n-2)- Anionile-membrane The following reaction will also take place: UO 2+ + 411+ + 2e --) U4+ + 2H 0. 2 2 This is possible since water is decomposed at the anode (H 0 - 2e- 0 + 2H+).

In addition, partial sepain- tion of uranium from iron by electrodialysis has also been made (at pH = 3-3.6), It has been found that during this process the cathode was covered with metallic iron; this method has yielded a decontamination factor for uranium from iron of about 1000.. Nitric acid solution have been treated analogously(80 g of U/1 and pH = 3-3.5T-.These tests have also been made with a two-chamber device having an anionite membrane. The average amount of energy needed to obtain 1 kg of nitric acid was less than 10 kwh. Application of multi-chamber electrodialyzers. Multi-chamber systems (as shown in Fig. 4) permit another decrease of energy consumption which is given by W = E(Co - 01074 n% kwh/l of distillate (E denotes the voltage, 7L the current output, and n the number of chambers). The authors have also investigated the rules governing the transfer of certain ions through a carboxyl membrane at different molar ratios of acid and salt. Amberplex A-1 has been used in tests with pure acids containing 5-6 g of uranium/liter and 1 g-equiv/1 of hydrochloric or nitric acid. A three-stage device schemati- cally shown in Fig. 5 has been used to reduce the acid content from 1 to 0.1 E-equiv/1- For 1 N hydrochloric acid'k, = 0.37 (first stage , for 0.7 N It2= 0.40, (second stage), and for 0.4 N A3 = 0.44 (third staged, the mean Card 3/8 22601 S/089/61/010/00,1/004/027 Application of ...

Current-voltage characteristics weTe taken in the 78-296K range. At 78K, the forward-current vs. voltage characteristic showed two slopes: 01 1.2-1.3 and B. 1.8-2.8. Crystal- structure defects are assumed to be responsible for the high-values of -0. At higher-than-room temperatures, the diffusion current describable by the'regular Shockley theory prevails. The reverse-current vs temperature curve measured texperimentally yields a forbidden-band width of 0-48 6v (at OK).' Orig. ar~. has:- 2 figures and 2 formulas.

The reaction to the irritation most frequently consisted of contraction of the vessels, but vas-odlIntion and two-phase reactions were also observed. Reactions of different types were obtained on irritation of the same points in the hypothalamis. Increasing the Inten- sity of the irritation or intravenous administration of dihydroergotoxin, hezonium, or aminazine often changed the nature of the reaction upon irrita- tion of the same point. After application of aminazine or hexonfum, a pre- dominance of pressor reactions was observed. Tie effect of the hypothala- mus on coronary vessels was not eliminated after exclusion of the influence ~of vascular innervation by section of the spinal cord or of the midbrain or ,application of pharmacological agents.

I'l FLI: I'l1'c Significance of central vcgct:ltive regulation disorders during exposure of the cardio- vascular system to ionizing radiation PERIODICAL Radiobiologiya, v. 2, no. 2, 1962, 228-233 Vascular and myocardial reactions to radiation were studied previously The present study deals with the changes in the hypothalamic pressor effect following irradiation. Experiments were performed on 33 niale rabbits irradiated with 800 r and 1000 r. Electrical, stimulation of the hypothalamic region before irradiation by inierted electrodes generally caused an increase in blood pressure. This was also absc;ved in irradiated animals. During the early stage of radiation sickness the pressure reaction was even greatc. thin in non-irradiat-W animals, while the stimulation threshold did not change- The cardiovascular reaction of irradiated animals showed a subsequent decrease in excitability of various hypothalamic tegions and variation of the stimulation threshold. This indicates adaptation disorders of the cardiovascular system during radiation sickness There are 2 figures and 3 tables. SUBMIT'FED August 2, 1962 Card 1/1 --,q.:I-..IIOVA, I.I.P.

Fizika tverdogo tela, V. 4, no. 6, 1962, 1675 - 1676 A n e v: technique of I-rowing tionocrystalline BaTiO layers is presented. 3 0 Alayer of BaTiO3po-,,-der on a platinum backing is kept at 16oo - 1700 C in an oxyEen atmosphere for 1 - 2 min. When the melt is removed from the heated zone of the furnace, it will form either a morocrystalline layer or a layer consistin,- of several large monocrystalline blocks. The platinum back-inr can then serve as one electrode. The other can be applied as a silver paste etc. The crystals obtained are cubic and turn into the ferro- electric tetr-nE;onal phase when cooled below their Curie point. Preliminary measurements aave a aielectric constant of 4000 - 6000 at 200C, 50 cps on a 20,,-thick soecimen. The dielectric constant decreases as the thickness of the s-,ecimens is reduced. At the same time the hysteresis loop becomes m~ore Card 112 BURSIAN., E.V.,,, SWRNOVA, N.P. Production of crystalline blocks of BaT103 from the melt in an catygen atmosphere.
