TEXT: This paper reports studies on the primary reaction involved
in the formation of the mixed Zn and Sr or-hophosphate base and
those reactions which are involved in the specific effect of the
reducing atmosphere on the phosphor compos:.tion. The base composi-
tion studied was Zn 0.44 Sr 2.56 (P04)2' Separare components of the
charge were roasted in air and consisted of,,. SrHPO .1 Zn

In the 3-component mixture, dehydration of tne Zn phosphate also
occurs. The reducing atmosphere used is a mixture of H 2 and N2'
Heating in H 2flow alone causes the prodj2t to become blackened
and lose luminosity. If subsequently roasted in a neutral gas at-
mosphere at 11000C, the white color of the product is restored, X-
ray analysis of produ3ts showed that the product obtained by heat-
ing in H 2 (3 - 5 hours) is Sr 3(P04)2 with Zn metai impurity, with

SrB. produced in the course of an investigation of methods for their pre-
paration (Ref. Ili Zhur. prikladnoy kbim. 31, 1958, 1293). The tests en-
played consisted in treating these compounds with acids and bases and
beating them separately with oxygen, nitrogen and carbon. Of these tests,
only the oxidation was studied previously. The bexaborides were used in a
powdery form (particle size 4C 4/A ) and analyzed as followai C&B a -

conducted at 9000C showed that the oxidation is proceeding at a fair rate
during the first 30 min. but attains a limiting value after 2 hours (39%
for CaB.9 42% for SrB,, and 46% for B&B.). This was explained by the for-
mation of a protective film of borates which, however, vanishes at higher
temperatures. (c) Stability of heating with carbon and with nitro gen.
I s I mixtures of borides with graphite were heated at 1700 0C to 2000 0Ci
also, borides were heated in a stream of N 2 at 800, 1000, 1200 and 1400 C.
The products were analyzed by chemical and X-ray analysis. No nitrides or
boron carbides were shown to be formed. Conclusions: The hexaborides of
Ca, Sr and Ba are shown to be even more inert than the borides of transition
metals. This fact is said to confim the author's previously expressed
view (Itef. 15: Zhur. neorg. khim. 34, 1957, 2) that the stability of a
boride increases with the number of boron atoms contained. There are 3

38 kcal, respectively) can only be achieved by adding Se. Most of the ZnO
is therefore converted into ZrSe. In 2ZnSeO 3+ 2S + Se, ZnS binds tLe
formed ZnO. Therefore, in the ratio ZnS i E2 SeO 0/ 1, only slight ZnO
impurities are formed, which do not influence the luminescence properties of
commercial sulfide selenide luminopbores. Without Se, ZnO will form by
sublimation with a slow temperature rise. Forced temperature rise and
average charges are therefore best:

TITLE: Study of reactions taking place during the preparation
of hexaborides of alkaline-earth metals by reduction
with carbon
PERIODICAL: Zhurnal prikladnoy khimii, v. 35, no. 1, 1962, 30-37
TEXT: Using chemically pure materials, the authors made a detailed
series of studies of the reactions which occur during the prepara-
tion of Ca, Ba and Sr hexaborides by heating mixtures of varying
composition of the oxides with graphite and B. The primary sinter,
liquid and gaseous products of hydrolysis and insoluble residues
were analyzed. The possible interactions are discussed. Using a
charge of optimum composition (CaO + 3B 203 + 5C), it was found that,,A
up to 15000C, the only reaction was between the metal oxide and
boron to form borates. Reduction with C commenced at 17000 but, at
this temperature, the products were boron carbide and graphite.
The optimum temperature for the formation of hexaborides was found
