Abstract :The solubility in the system (HH4)2BeF4 (1) - NH4NF (II) -
H2) was studied at 25 41 o.10. The solubility of I In water
is 32.3%. The dissolution of TI in water is accompanied by
a slow decomposition. No decomposition of II was observed
in solutions containing I. No new compounds and solid so-
lutions were found in the system; the bottom phases are I
and II. The solution saturated with respect to both the
salts contains (in % by weight) 19-31 of MW, 12.31 of BeF3
and o.26 of mnF The obtained data can be applied to the
determination OFconditions of separation of fluorine can-

ABSTRACT: In the present paper the thermal investigation of the system
Becl 2-BeF2was carried out and the phase diagram was plotted.
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.

ABSTRACT: By way of introduction the field of application (synthesis of
tellurides with sem-Joonducter properties) is mentioned, and the
main admixtures in tellurium (Ref 1) are enumerated. 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 initi.al. tellurium
was highly oxidized arA contained a great amou-nt of tsllur4~,Jm

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. There are 3 figures,

ABSTRACT# The purpose of the present paper was an investigatio*f the
solubility of the system CaS04;-BeSO4_H20 and the explanation
of the influence exerted by these sulfrLtes, upon each other.
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

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). There are 4 fig-
ures, 3 tables,and 16 references, 2 of which are Slavic.

ABSTRACT: The distribution of selenium impurities in tellurium in vacuum
distillation was examined. 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. Tellurium and selenium are

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

ABSTRACT: The system NaF-BeF2 was investigated in the crystallization
range of beryllium fluoride.~ Purest sodium- and ammonium-
beryllium fluoride were used for the investigation: Na 2BeF4
and (NH 4)2 BeF 4~~ The differential thermal analysis was carried
out by means of the pyrometer by Kurnakov. It was found that in
the case of the thermal treatment'of Na 2BeF4 besides the thermal
effects at 220 and 3260C also an endothermal effect" at 2700C
occurs on the thermograms. Na 2BeF4 melts at 610 + 50C. The
results of the thermal analyses of the melt of the system
NaF-BeF2 are given in table 1. The phase diagram of the system

ABSTRACT: The Me+F-BeF2 systems can be regarded as weakened fluoride
"models" of Me 2+ O-Sio2systems with Me 2 representing Li,
Na, K and Rb (references 2-11). 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

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

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. With regard to the axes

of the radii. Figure 2 shows the dependence of the
destruction temperatures of the crystalline lattices of
the fluoreberyllates (congruent melting, incongruent
melting, decomposition in solid state) on the cationic
radii. The diagram shows that the compounds of the MelBeF 4
are most stable. This stability is increased from Li
to Rb, and is decreased insignificantly from Rb to 09.
For MeBe 2F5 compounds there is hardly any change of the
decomposition temperature from Li to K. Compounds of this
Rb and Cs combination are considerably more stable and melt
congruently. There are 2 figures, 1 table, and 15 referenceg

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~

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

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. Besides a compound
