TEXT: The Droblem whether magnetite has orthorhombio or rhombohedral
structure below 1200K owing to electron ordering is studied. For this
purpose, the anisotropy of the even effects (AR/R,,6a/a and 6111) for
crystals with orthorhombic and rhombohedral structure is calculated by a
method proposed by N. S. Akulov (Ferromagnetizm.- Ferromagnetiem, GITTL,
M.-L., 1939)4 According to this,'the relative change of an even effect
caused by A transition from the paramagnekic state into the ferromagnetic
saturated state is given in linear approximation by

ABSTRACT: Although information is available on the salts of trihydroxy-
glutaric acid, the only complex compounds which have been des-
cribed are the salts with trivalent iron and with copper. In
the present investigation 99.87% pure gallium was'converted
into the nitrate and used for the preparation of-complexes with
trihydroxyglutaric acid, the-reactions being followed by con-
ductometric and potentiometric titrationp electrical conduct-
,ivity measurement and hydrogen-ion concentratimi determina-
tions by the isomolar series method; a preparative method and
subsequent investigation of the complex synthesised were also
used:.

ABSTRACT: From January 28 to Februaxy 1, 1958 the Third, Conference of the
Ukrainian Republic on Inorganic Chemistry in collaboration with
the Departments of Chemical and Geological Sciences of the AS
Ukraine SSR and the Institute of General and Inorganic Chemistry
of the AS Ukraine SSR took place at Kiyev.
About 200 collaborators of the scientific institutes as well as
pedagogues and representatives of the chemical industry from
Kiyev, Kharlkovi L'vov, Dnepropetrovsk, Stalino, Odessa and
other towns of the Ukraine as well as from Moscow and Leningrad
attended the conference*
The work of the conference was carried out within two sections
of the plenary meetings: 1) The structure of inorganic compounds

minerals. 42 lectures were held at this conference, 18 of them
at the plenary meetings. The conference decided upon intensifying
the research of inorganic compounds especially within the field
of non-ferrous and rare elements, as well as in the chemistry
of complex compounds; the process of complex fo:rmation and the
equilibrium of solutions should also be intensified.

ABSTRACT: The physico-chemical properties of the hydro.,grearboxylic
acids and their compounds are only little investigate'd.
From this series the tartaric acid is investigated best.
The physico-ohemical properties of the trioxyglutaric
acid which differs from tartaric acid by the presence
of another H-C-OH groupq are hardly known, There exists
a number of Avestigations indicating the possibility
of production of cheap trioxyglutaric acid and i 'ts appli-
cation in some cases instead of tartaric acid and citric
acid. In the present work the author wanted to determine
the first and second constant of the acid dissociation

TITLE: Separation of rare-eak-th elements with cadmium

PERIODICAL: Ukrainskiy khimicheskiy zhurnal, v. 28, no..3, 1962, 301-305
TZXT: Attempts were made to separate rare earths (RE) with cadmium
hydroxy chloride in the presence of sodium chloride. The distribution of
lanthanum, praseodymium, and neodymium between solution and precipitate
was determined after precipitation of their basic salts or hydroxides
from solutions containing 2, 3, and 4 g-ion of Cl/1-ter by shaking 2 ml
of cadmium oxychloride for,2 hrs with 5 mi Of 5-10-~ molar solution of RE
chloride, then centrifuging,filtering, and determining the RE concentra-
tion colorimetrically as aluminonate. Results: The equilibrium ratio
Ln /Ln of the sameelement increases with increasing concentration
prec dis
of Cl ions. With equal 01 concentration, the distribution coefficients of
the individual RE elements differ significantly. For La-Pr with

2, 3, and 4 g-ion of Cl/liter these are 12, 15, and 11. For La-Nd with
2, 3, and 4 g-ion of Clj/liter they are .16, 29, and 11. For Pr-Nd with
2, 3, and 4 g-ion of Cl/liter they are 1.3, 1.9, and 0.9. Further, the
separation of lanthanum - praseodymium, lanthanum - neodymium, and
praseodymium - neodymium was studied in a ten-step countercurrent process.
5 ml of RE - NaCl solution (total 01 concentration 3 g-ion/liter) was
added to 2 ml of cadmium hydroxy chloride, centrifuged, and the solution
filled into the-following test tube. Thus, 10 precipitates and 10 solutions
were obtained and studied as regards RE. The precipitates were dissolved
in dilute hot ENO3 and the RE separated from cadmium by a large NH 3 excess
(p'Iq- 9); the hydroxides were annealed to oxides and these were dissolved
in dilute ENO 3' The contents in praseodymium and neodymium were determined4
spectrophotometrically and the content in lanthanum calculated from the
difference. Results: (1) Complete precipitation of neodymium is already
effected in the first four steps. (2) Under these conditions the
4
precipitation of lanthanum is incomplete as some of it is still in
soluill6n. (3) The precipitates contain 87% of the initial amounts of RE
elemeilis, and the solutions 13%- (4) 70% of the RE are contained in the

2.0 in 111; 1.07 in PII; 1.21 in PIII, and 0.42 in PIV. (7) When
praseodymium is separated from neodymium, 93-5% of the total amount is
precipitated in the first 5.steps.. The Nd 2 03 1 Pr6ol , ratio is:
1.33 in the initial solution; 1-45 in PI; 1-57 in P11; 1-43 in PIII;

TITLE: --rFe--effact of the size factor on irreversible
changes of shape due to therinal cycling
PERIODICAL: Fizika metallov i metallovedeiiiye, v. 12, no. 4,
1.961, 541 - 549
TEXT: Metal components subjected to thermal cycling may
Irreversibly change their shape and/or dimensions. When these
changes are caused by relaxation of internal stresses of the
first type, i.e. those set up as a result of a temperature
gradient in -the component, their magnitude and sign should be
affected by its dimension. Published data on the effect of this
factor (Ref. 4 - authors - Nauchno-tekl.-inichoskiy inXormatsionnyy
byulleten' (razdel fiziko-matematicheskikh nauk), Leningrad
politekhn. in--t, 1958, no. 12, 56; Ref- 5 - G.P. Lazarev -
Izv. AN SSSR, OTN, Metallurgiya I toplivo, no. 5, 1959, 57) are
contx-adictory and since this problem is of both theoretical and
practical importance, the investigation described in the
present paper was undertaken. The experiments were conducted on
