Purest beryllium hydroxide was used as initial material for the chlorides and fluorides. Beryllium hydroxide was converted into beryllium oxide by annealing at 10000 C, and was then converted into beryllium chloride by chlorination with carbon tetrachloride at 10000. Beryllium fluoride is obtained by thermal decomposition of (ITH 4)2 B43F4in vacuum. The thermal analysis of the system BeCl 2-BeF2was carried out by means of Xurnakov PK-52 pyrometer with platinum-platinum-rhodanid. The fluorides and chlorides of beryllium form a simple eutectic with the composition Card 1/2 72.5 mol% BeP., and a melting point at 3MOc. Thermal Analysis of the System BeCl2_BeF 2 SOV/156-58-4-12/49 The thermal analysis shows a weak endothermal effect at 1100 Cp which indicates the transformation of unstable beryllium fluoride into a highly stable form. The melting point of beryllium fluoride was determined to be 4210C. The heatingeurves of the samples show effects at temperatures higher than the liquidus temperaturep which indicates the boiling of the BaCl -BeF2 melt. In the case of a higher beryllium chloride content no solid solutions were found by means of X-ray analysis. There are I figure, 1 table, and 8 referencest 4 of which are Soviet.

The purification methods are recalled (iefa 2, 6). Due to the fact that tellurium, both in the liquid and in the solid state, possesses EL considerable vapor pressure (Refs 7-10), sublimation constitutes a most efficient DUTificatior. method. The authors szudied the process mentioned in the tit1G and the tellurilm distribution in -che condensation zone. The tellurium was highly oxidized arA contained a great amou-nt of tsllur4~,Jm dioxide. It was chemically purified and investigated with regard to selenium admixtures.

However, halogen and selenium admixtures cannot be determined by means of spectral analysis. In an earlier study (Ref 13) it had been found that no separation of selenium from tellurium occurs on sublimation. As already mentioned, the selenium content in tellurium could, however, be lowered to 2-10-4% by means of chemical purification. Due to the different,volatilities of their dioxides selenium and tellurium can be separated (Refs 14-18). The purification of otheradmijitures (Ref 19) is discussed.

The solubility-was investigated at 25 and 750 C. In the system CaS04-BeSO -920 the elimintted solid phase at 25 and 750 C in pure CaSS and neither double salts nor solid sol- utions could be determined. The CaSO , eliminated at 25* C crystallizes with 2 Mol of water. Tit CaSO 4 eliminated at 75w C represents asloium-sulfate anhydrite. Chemically pure beryllium sulfate and calcium sulfate were used as initial substances. CaSO was produced by way of calcium chloride and sulfuric &oil. The determination of beryllium in the solution is performed voluaetrically. But the determination Card 1/2 of calcium is performed with the aid of the radioactive Investigations an the System CaS04 -BoS0020 78-2-19/43 indicator C&45. For the separation of beryllium and calcium, calcium oxalate in first precipitated with the aid of ammon- ium oxal&te in a neutral solution, whereas beryllium stays in the solution an a soluble complex. On addition of beryll- iua sulfate to the calcium-sulfate solution at 2% of beryllium sulfate a minimum of the solubility of C&W4 occurs, then the solubility again increases to 5% of beryllium oulfate,and then it again decreases. Crystallographic analyses also show- ed that the solid phase only contains calcium sulfate and that neither double salts nor solid solutions occur between CaS04 and BeSO It was found that the solubility of calcium sul- fate at addition of beryllium sulfate at 25* C in com- parison with the solubility in water is almost reduced six times (209 mg1lOO g solution in water as compared Ito 11 mgl 100 g solution) and that it is 13 times reduced at 75 C (200 mg as compared to 15 mg/100 solution).

The quantitative determination of the distribution of selenium in tellurium was achieved by means of radioactive isotopes of selenium. The corresponding dis- tribution curves of tellurium and the addition of selenium, depending on the condensation temperature, were drawn on the basis of the results obtained (Fig 1). Attempts at commercial purification of tellurium with 098% selenium by vacuum distillation did not yield a aervioeabla separation efficiency. The distillation was carried out at temperatures of 520 to 5400C. Vacuum distillation does not effect a separation of selenium impurities in tellurium.

Beryllium oxide is chlorinated at a temperature of 700-BOOOC in a quartz boat with carbon tetrachloride vapor and with nitrogen as a carrier. The beryllium chloride formed - BeCl 2 is removed from the zone of reaction by sublimation. The re- actor for the reaction is placed vertically. This apparatus for chlorination of beryllium oxide in the boiling layer shows that after 20 to 25 minutes almost 95% of all the beryllium oxide has been chlorinated. A chlorination of beryllium oxide in a horizontal reactor, however, does not supply a quantitative yield even after several days * There are I figure and 3 references, 0 of which is Soviet.

The first system mentioned in the title above was to be investigated from the aspect of the changes of stability of different fluoroberyllates. In this system four compounds were found: Cs 3BeF 59 Card 1/5 CS2BeF3, CsBeF3 and CaBe 2F5* They all could Thermal and Roentgenophasio Analysis of the CsF-BeF 2 20-119-5~a/59 System and Its Interrelations With the MIF-BeF2 Systems easily be produced by fusing together the component mixture in stoichiometrical proportions. The investigation of the system in the 0 - 33 % BeF2 range is renderod difficult by the extreme hygroscopic properties and other disturbances. Thus a part of the diagram (figure 1) is only based on the cooling curves. The other part is based on the heating curves. For CsF the the melting point was determined to 6880C (similar to reference 13). With 14% BeF 2 and at 5980C Oaf formed a eutectic with Cs 3BeF . This melts incongruently at 6590C- At 6170C this compouna suffers a polymorphous transformation. For Cs 2BeF4 the melting point was determined to 7930C. Its polymorphous transformation took place at 4040C. CsBeP 3 melts congruently at 4750 C and shows two polymorphous transformations. The eutectic of Ca 2BeF4 + CsBeF 3 is at 449 0C and with 48% BeF 2- CaBe2F5 shows its polymorphous Card 2/5 t1ransformation at 4500C, melts congruently at 4800C and Thermal and Roentgenophasic Analysis of the CsF-BeF 2 20-118-5-24/59 System and Its Interrelations With the NIP-BeF !7-yatem 2 forms eutectics with CsBeF 3 and BeF 2* The great similarity between the phase diagrams of the CsF Be? 2 system and of the CsF-ZnF 2 system is striking (refe;ence 14). The individuality of the ceasium-fluoreberyllates was confirmed by roentgenophasic analysis. It was found that the quartzous BeF 2 exists only up to 58000 and melts at higher temperatures. The cristobalite-like form occured only up to 5350C and slowly changed into the quartzons form (from 1500C up). It could not be determined, whether the dis- appearance of the cristobalite-like form of BeF 2 above this temperature is caused by its melting. The polymorphous transformations of CsBe 2F5 and CsBeF3 were confirmed by X-ray analysis at high temperatures. Moreover the absence of polymorphism with CsF up to 4000C was proved. For Ca 2BeF4 and CsBeF3 the values of the axis parameters of the lattice were determined, which proved to be rhomboid. The pycnometrical density was measured.

TITLE: --------------- Compounds of Beryllium Hydroxy Acetate With Sulfur Dioxide (soyedineniya oksiatsetata berilliya s sernistym angidridom) PERIODICAL: Doklady Akademii nauk SSSR, 1958, Vol 122, Nr 3, Pp 397-39~ (USSR) ABSTRACT: Affiliation products containing mainly amino nitrogen are de- scribed for beryllium hydroxy acetate (Refs 1-3). These com- pounds are stable enough and are probably formed at the ex- pense of the free electron pair of nitrogen. However, for the substance mentioned first in the title compounds of a weaker binding may be expected, namely of the type of the so-called "inclusion compounds" (soyedinaniya vklyucheniya Pl.) (Refs 4P5). The compound mentioned in the title probably is such an "inclusion compound" (Ref 2). This problem is discussed in detail in the present paper. In the concentration by the evaporation of a solution of beryllium hydroxy acetate in liquid sulfur dioxide the latter compound is precipitated in Card 1/4 form of well developed octahedrons. The thus forming compound SOY/20-1?2-3-20/57 Compounds of.Bexyllium Hydroxy Acetate With Sulfur Dioxide is extremely instable at room temperature and decomposes into its two initial products. This makes difficult the determi- nation of its -composition and the preparative isolation by means of thd-usual methods of chemical analysis. In order to investigate the interaction of both substances mentioned in the title the:authore studied the method of the construction of diagrams.,.at a constant temperature: composition - vapor pressure in the-sYstem formed by them. For this purpose they used the , Ruettig tensiometer (_te~nzievdiometr) (Ref 6). The working process is described. The equf~ri= Gould be observed after 1C-20 hours* Figure I shows the isothermal lines of the composition versus pressure function for -9.5, -15,,-20 and -300. From the general view of the isothermal lines it dan be seen that in the case of a concentration by evaporation of one of the mentioned saturated solutions a comp(rand Be 4O(CH 3C00)6 .2 S02 is precipitate-'. :Thust it was observed that the compound 3Be 4O(CH 3GOO) 6'4302 (described by the authors in reference 2) represents a product of a partial decomposition of the compound of beryllium hydroxy acetate with molecules of sulfur dioxide.
