TITLE: Precipitation of elements from fused salts. Report 1. Precipitation of some elements from fused ammonium nitrate PERIODICAL: Akademiya nauk SSSR. Sibirskeye otdeleniye. Izvestiya, no. 4, 1961, 38-42 TEXT., This article reports on an investigation into separating rare earth metals by means of precipitation of their insoluble compounds by different precipitants from fused ammonium nitrate. It is known that rare earth oxides react with fused ammonium nitrate f0rM3_n luble double nitrates as cited by L.-Ordit and Ya. Kleyn- ,& so berg L Abstracter's note: Names taken from Russian_7 (Ref. 1: Nevo- dnyye rastvoriteli (Non-aqueous Solvents) IL, M. 1955). At high temperatures double rare earth nitrates react with ammonium sul- phate at the formation of double rare earth sulphates, e.g. double Card 115 22341 S/200/61/000/004/001/005 Precipitation of elements... D228/D305 lanthanum sulpahte at 3300C as cited by V. K. Valltsev and V. P. Kovyrzina (Ref. 4: Izv. SO AN SSSRI No 10, 1960). The same reaction in fused ammonium nitrate used as a solvent takes place at 1800C. The use of fused ammonium nitrate allows work at lower temperatures, mainly at 1800C. The following experiments were conducted: Rare earth oxides previously ignited to 9000C - La203, Nd203, Er203, DY203 and alkaline earth oxides - MgO, CaO, SrO, BaO, uranium nit- rate and thorium nitrate, were dissolved in fused ammonium nitrate at a temperature of 1800C concurrently with the formation of soluble double nitrates. The solubility of double lanthanum nitrate is 60% by weight. The oxides do not react with fused NH4NO3. The reactivity of uranium oxide with fused ammonium nitrate is very low. The solution of Th and U was produced as follows: hydrated nitrates of U and Th were fused with ammonium nitrate at 2500CI twice, to a dry cake, a part of which (assumed to be double nitrates) was sol- uble in fused solvent. A precipitant in the form of salt or dis- solved in fused ammonium nitrate was then added to the solution of metal nitrates. The precipitate formed was separated from the C ard 2/5 22341 5/200/61/000/004/c-,01/905 Precipitation of elements ...

Ammonium oxalate precipitates La, Nd, Dy, Ca,-Mg, Sr, Ba, Thorium. Double thorium oxalate is*soluble in.the excess of precipitant. Uranium under.these conditions is not precipitated. AlIcali oxalate can be used instead of ammonium oxalate vith exactly the same results. Time of precipitation varies from immediate to 30 hours for differt'-.nt rare earth metals. The authors conclude that on the basis of new ideas on 'the structure of solvents, it may be suggested that this ratio varies also, depending on.the precipitant concentration. The different behavior of rare earth metals during precipitation by diff&rent precipitants opens up new possibilities for tlieir separation.

Izvestiya, no.~6, 1961, 71-74 TEXT: The purpose of this work was the study of the distribution of the reaction products of rare-earth oxides (La, Fr, Nd, Sa, Er and Y) with fused ammonium nitrate irt the process of zoned crystal- lization. There appears to be little: published information concern- ing the application of zoned crystallization for separating and purifying rare-earth elements, although the method has been employed by Sue et al (Ref. 1: P. Sue, 1. Pauly, Bull. Sac. Chim. de France, No. 5, 593 (1958) for isolating other elements with similar chemical properties, Further research by V. Val'tsev and V.

D206/D303 thanum, and in certain data regarding its solubility in fused ammon- ium nitrate. The experimental procedure adopted by the authors com- prises the initial solution of rare-earth oxides in molten ammonium nitrate; the cooling of the melt in an aluminum boat, with the form- ation of a semi-cylindrical slab having a length of 32 cm; the refu- sion of the slab at 170 - 1900C in a molybdenum-glass tube by means of a heater which is fitted with a thermocouple and rheostat to L/ ensure smooth temperature control and which is moved over the slab at a speed of 0.82 cm/hr; the removal of the slab from the boat after a period of 45 hours; and the subsequent dissection of the slab into ten equal parts which are then analyzed for the rare-earths. During the passage of the salt slab through the molten zone the rare-earths are redistributdd in such a way that thcir concentration at the end of the slab considerably exceeds the original value. The distribution curves for the nitrates of Nd, Sa and Y are shown graphically. The coefficient of enrichment (K) - necessary for com- paring the behavior of elements in the process of zoned crystalliza- tion - was calculated from the ratio of their inital to final con- centration. After three slab runs through the fused zone the dis- Card 2/4 23631 S/200/61/000/006/003/004 Distribution of lanthanoids ... D206/D303 tribution of elements at 'the end of the slab is in direct linear relationship to their atomic weights (A): K a 0.063A - 7.33. This relationship also holds for a slab of heterogeneous composition prepared in a slightly different manner. Coefficients of separation - the ratio of the enrichment coefficients for certain pairs of ele- ments - were found in order to appraise the possibility of purifying particular elements. They reach a maximum when nitrates are cryst- allized in a heterogeneous slab, after no less than nine runs through the fused zone. The pairs Sa - Y and Nd - Sa were therefore subjected to zoned purification under these conditions which are evidently the most favorable for purifying certain pairs of rare- earth elements. A relatively pure separation is effected in the case of samarin and yttrium: the yttrium content rises from 97.176 to 99.276, whi-le the samarin concentration falls from 2.976 to 0.8%. The removal of neodymiuin from yttrium, however, was not successfully ac'complished. This is believed to be due to the fact that the dis- tribution of rather large amounts of rare-earths in ammonium nitrate differs from the normal distribution specified by existing equations (Ref. 6: Metody polucheniya. chi'stykh metallov (Methods of Obtaining Card 3/4 23631 S/20OJ61/000/006/003/004 Distribution of lanthanoids... D206/D303 Pure Metals), Sb. perevodov (Collection of translations), IL, 1957) which.are only applicable in the case of a low concentration of im- purities in a slab in the process of zoned crystallization. The authors conclude that their method is only suitable for separating some elements of the yttrium and cerium groups; it is not recommend- ed for purifying mixtures consisting of elements from other rare- earth groups with very similar properties.

Sibirskoye otdeleniye, Izvestiya, no. 9, 1961, 47-52 TEXT. Thermal methods of synthesizing the rare-earth maleates have been little studiedg so the authors investigated this problem by physico-chemical research on the reaction of La203 with maleic acid.The analyses were carried out in accordance with V.S. Kurnakov's thermographic method Abstracter's note: No reference given with supplementary volumetric, crystallographic and chemical techniques. The experimental apparatus includ- ed the pyrometer and recording buret, described by L.G. Berg (Ref.2: Termo- grafiya (Thermography), Moscow, 1937; Ref. 31 Tr. Kaz. fil. AN SSSR, vyp- 3, 1956), and G.B. Bokiyls polarizing microscope (Ref. 4s Immercionnyy analiz (Immersion analysis)q Moscow, 1951). It was first established that the Card 1/4 27732 B/200/61/'000/009/002/003 D219/D301 Thermographic investigation of the reaction... reaction between La.203 and maleic acid begins at 110? Next, mixtures con- taining variable amounts of these compounds were heated for 20 minutes at 1300 and then analyzed crystallo-optically, when two products--termed A and B--were detected. Their refractive indices are 10577 and 1,446, both substances being soluble in water but insoluble in alcohol, acetone and ben- zene. B, present in very small quantities, may be due either to A's reac- tion with excess maleic acid or to Ala thermal decompcsition. Additional tests, involving the a)ntinuous heating of samples to 3500and the use of CaH2 and P205 absorbers, indicated the dissociation of A first at 145', when wa- ter is evolved, and then again at 1960; C02, however, is only given off at temperatures of 2600 and above. It was further ascertained that A partly decomposes at 1450 into B, which itself dissociates into water and C02 bet- ween 1960 and 260? The maximum evolution of heat from the reaction is ob- tained if the original materials are taken in strict stoichiometric pro- portion: the greater the divergence from this ratio, the less likely the decomposition of A. According to the results of the authors"chemical ana- lyses A has the formulag La2(C404H2)3 . 1-23H4C404' Its aqueous solution Card 2/4 27732 5/200/61/000/009/002/003 D219/D301 Thermographic investigation of the reaction... gives a pH of 4 and intensely decolorizes permangmte. Conclusions. 1) The JAnthanin maleate thus synthesized differs from the usu4l neutral- salts prepared from rare-earth oxides and ammonium compounds in that it is a double salt--of La2(C4O4H2)3 and H4C404, 2) The thermal decomposition of the double salt proceeds through the splitting-off of maleic acid, which simultaneously breaks down into the anhydride and water, to the formation of a new compound that also dissociates at higher temperatures; the nature of this substance has yet to be determined. 3) The authors stress the impor- tance of this reaction between rare-earth oxides and molten acid to form new compounds with new properties: e.g. the solubility of these secondary products is negligible in comparison with that of the primary products of the interaction of rare-earth oxides with certain organic acida.

The following mixtures were tested (1) La 2.5, Pr 8-11, Nd 86.84, Sm. 2-3, and (2) Pr 3.66# Sm 29.3 Eu 1.0, Gd 24.3, Dy 5.77v Ho 0.5, Eb 4.7, La, Tb, Yb 1, Y 25.2. The melts were cas-u into rods which were then zone crystallized 6-9 times, passing the zone at 5 cm1hr. The experimental method for chloride melts is indicated; for the other two the procedure was that used earlier. Sections of rod were then analyzed spectrogra- phically for the lanthanons. The results are tabulated and discus- S1200162100010021002100311 Zone crystallization of lanthanon D204/D301 sed In N114NO3 the heavier elements tended in general to concentra- te at the end of the bar and the same was observed for Sm (mixture (1)) in the NH4CNS melt. 6imilar tendencies were observed for the chloride melts although the results were only qualitative. It is corcluded that (a) zone crystallization from NH 4 NO3or NH4CNS is promising owing -Go the low temperature of the process. The chloride nrocess is further made difficult due to the hygroscopic properties of the lanthanon chlorides. (b) Concentration of the heavier ele- raents at the end of the bar is probably due to their lower m.p.'s although discrepancies to this rule were observed. (c) Relative proportions of the lanthanons (mixture (1)) in NH 4NO3and NH4C"S melts were relatively unaltered after zone crystallization, The dis- tribution is probably affected rather more in the high temperature chloride process, Analytical work was carried out by R.R.

Designed by the Gipromez Institute, these were the first Soviet reheating furnaces with a reel inside. The furnaces reheat metal in th- rolling process on the finishing stand of a 1200 strip mill consisting of two stands. Slabs,600-1000 mm wide, 100-140 mm thick, 2.0-2.3 m long an-j weighing up to 2.5 t1are heated in a holding furnace and rolled in a rough stand to 10-11 mm thickness.
