A. V. NOVOCELOVA'S WORK O11 THE CHEDLISTRY OF l;ERyLLiNd
A, V. Novoselova was elected Corresponding Member of the Academy of
Sciences USSR, in the specialty of general and inorganic chemistry, at a
meeting of the Lepartment of Chemical Sciences of the Academy geld cn
19-20 October 195,3,
Novoselova has concentrated particula~?ly on work dealing with the
chemistry of rare elements. She has carried out extensive research on
the chemistry of beryllium and its compounds. In the course of this work,
she investigated the interactior, of silicon fluoride and sodium fluoro-
silicate with beryllium oxide at high temperatures. Application of thermal
analysis to the study of the system consistin;., oi' sodium fluoride and be-
ryllium fluoride and R-ray irvestigntion of the phases formed by this sys-
tem enabled Novoselova to establish the existence of the compound NaF.2BeFp,
which was not known until then. She also established the existence of
polymorphic modifications of sodium flurobe:?yllate and beryllium fluoride
and of a new modification of anhydrous beryllium fluoride which crystal-
lizes in the hexagonal system. Novoselova has conducted extensive research
on ternary systems consisting of water, brryll.ium fluoride, r-nd fluorides
of other metals, In almost all of the ternary systems studied, ^ew com-
pounds not described before were discovered. The results of the work done
by Novoselova in this field contributed to the understanding of leaching
(extraction) processes.
In addition to beryllium fluoride and its derivatives, Novoselova has
also subJected to study other beryllium salts, pa:?ticularly sulfates, She
investigated Por that purpose the following water-salt systems formed by sul-
fates of other metals [with beryllium sulfate?]: two terna:?y systems, one
quaternary system, and one quinary system. Hy carrying out this work, very
valuable data were obtained which characterize a number of new double sulfates.

bery;,lium salts, Tensimetric investigation of sulfates and nitrates of beryl-
lium was carried out by Novoselova in the course of this work.
