TITLE, Electrolytic precipitation of chromium and vanadium
from molten slags

TEXT. An electrolytic separation of vanadium under reducing and
oxidizing conditions as well as simultaneous pre..-ipitation of
chromium and vanadium from a works' slag were investigated. In
the initial experiments the starting slag contained 40% CaO,
15%0 A120 5% M&O and*40% S102- To this slag an addition of
10 to 2U'V205 or 5% Cr203 and-5% V'205 was made, The
electrolysis was tarried out in corundum crucibles placed in a
carbon resistance furnace heated to 1600*C. T%mgsten wire was
used for electrodes. It was found that under raducing conditions,
the current efficiency for vnnadium (about 8o%) is practically
independent of the -,urrent density. Under oxidizing conditions

oxidation of the reduced product by the gaseous phase. On
simultaneous separation of chromium and vanadium with increasing
zurrent density, the current yield of vanadium sharply de,~reasea V/
and that of chromium remains practically constant. At a current
density above 1.1 A/~rm2" silicon begins to be reduced. This
indi-:;ates that vanadium is mainly separated an the cathode at a
.:.urrent density below 1.1 A/,~zm2 and mainl)r chromium is separated
at a higher current density, The works waste slag on which the
electrolytic separation of vanadium was tested had the following
mean composition. 23% S102, 11% Cr203, 1.2% V205, 18% T102,
1.5% 140, 2.5% A12039 1.6% CaO and 35% of total iron. Since
electroly,tic separation of Jron 1-8 at present uneconomic, a
preliminary redu-c-tion of iron with carbon is necessary. It was
experimentally established that the slag had a melting -temperature
of 15204C and thdt it was very via-.ous, To improve the reducing
conditions the slag was mixed with 10% of a bladit-furnR..* Alag
(40% CaO, 395*' S102 and 12% A1203)- The slag mixture, with an
addition of some char~.oal (amount not ape.-.ified) was melted in a
10 kg furnace and retained for 1.5 hours at 1500'C, The reduced

metal contained 2.5 to 4% Cr and 0.5 to 0.7% V and the residual
slag contained 0.2 to 0.3% V20q and 4 to 5% Cr2O3. In the
subsequent experiments, after retaining the charge for 1.5 hours
at 1500*C, a graphite anode was Immeraed"into the slag and a
direct current was applied (current density 0.8 to 0.9 A/cm2).
On the application of the current, the content of vanadium in the
slag decreased to 0.09 to 0.10% and increased to up to 1% in the
metal. It is concluded that the electrolytic method can improve
the extraction of vanadium from slags. There are 3 figures and

composition of the Mn-Si and Fe-P alloys are attributed to a sharp
rise of the rate of increane of covalent bonds. Up to a
com-position corresponding to chemical compounds a relatively small
part of the electrons pair off and the compoundm MnSi and Fe 2P
are paramagnetic compared to pure re and Mn. After forming
chemical compounds the number of paired electrons starts to increa-~e
rapidly and the paramagnetism of the alloys decreases sharply,

diamagnetic and FeP is less paramagnetic than Fe zP, Thus, the

TITLEs Use of solid electrolytes in emf measurements
PERIODICAL: Zhurnal fizicheskoy khimii, v. 35, no. 12, 1961, 2710 - 2712
TEXTj Slags used as electrolytes for the examination of melts in
ferrous metallurgy by emf measurements have the drawback that they react
with the cell walls making the measured emf values unstable. In a
previous study (Zh. prikl. khimii, 31, 689, 1958), the authors obtained
well reproducible emf values by using a mixture of Al 203with 5~'
refractory clay as electrolytes Al Al 203 + clay Fe, Csat 9 Al (2). In
the present paper, the authors checked data obtained with this element
and compared them with those obtained with a liquid slag of 40i"a CaO,
40% Al2039 15% B2OV and 5% MgO. Results are given in the table;

Molten copper was used as cathode. Temperature was 1350-15500C, the cur-
rent density, 0-13-0-40 a/CM2, Determination of the diffusion coefficient

found with an oscilloscope. D is onloulatod from to, Co, and is

recorded by a loop oscilloscope, auplification being carried out by
6 H9 (6N9) and 6 P7 (6G7) tubes. Results aro given in Fig. 1 as

TITLE: The Struotmre of the Surface Layer of Molten Niobates
-PERIODICAL: Doklady Akademii nauk SSSR, 1961, Vol. 136, No- 3t
pp. 644-646
TEXT: The authors deal with the problem of the formation of electric
double layers on the interface between melt and air. According to
published data, mainly oxygen anions will be found on the surface of the
melt. According to Ref. 8, however, a displacement of the oxygen anions by
large monovalent alkali cations ought to be possible. It was the purpose
of the present work to check this assumption experimentally. The method is
based upon measuring the surface tension a and the surface potential 6s on
the interface between melt and air in the systems OB20 - Nb205J
K2 0 - Nb205; and CaO - Nb 205 at 150000, the concentration of Cs 20, 120
and CaO having been varied between 0 - 50 mole%. Experiments were made in a

according to Ref. 99 determined by measuring the maximum pressure in

nnTB-1 (PPTV-1) potentiometer, and referred to the potential F-9 of the
gas electrode. Aa = f- + e8 - f9 ;~- 0. AEO = 60 + PIO - Eg remained constant.

them the conclusion is drain that the outer plate of the double layer is
formed by oxygen anions. With increasing conoentration of Cs+ or K+ ions,
a partial substitution of the 02- anions occurs. The number of lZatione
adsorbed on the interface, their surface conoentration NS, was calculated
according to two methods. 1) Accordin to the Gibbs equation for ideal
solutions.. r. -CIN(l - N)/R~]ao/aN; 2~ on the basis of the change Aq of
the surface charge on ihe assumption that the double layer may be put

No is the Avogadrofs number, e the electron charge; the number 2 takes
account of the number of ions in the molecule Me20. The results of these

From the differences betieen Ns and Nb the following conclusions are
drawn.: The Me+ ions replace, above all, niobium cations in the double
layer, which are deeper and more distant from the surface than the 02-
anions. Only a small part of the Me+ ions displaces 02- ions from the
surface. The adsorbed Me20 are thus mainly orientated toward the surface
with their oxygen anion. The more difficult displacement of the oxygen
anions from the surface of the melt is explained by their easy
polarizaVility. There are 1 figure, 1 table, and 13 references: 7 Soviet,

TITLE: Diffusion of Hydrogen in Molten Slag
PERIODICAL: Doklady Akademii nauk SSSR, 1961, Vol. 136, No. 4,
pp. 866-870
TEXT: Data available in the literature concerning the mass transfer of
hydrogen in molten slag indicate very hig 10-3 - 10-2 cm2
,h values ( sec-1).
These data were obtained under the conditions prevailing in open-hearth
furnaces, and rather stand for convection than for molecular diffusion
DR. To eliminate convection entirely and to approach the value for DR, a
nonsteady diffusion was used in the present work An A1203 test tube
contained a thin layer of viscous, liquid slag 1-5 mm, 3 - 100

water liberated from the slag to a hygrometer. The dew point was used to
calculate the rate of water yielded by the slag.

very high (1.0; 1.1; 0.9 )-10-5 cm2/sec. V H2 0 was not dependent upon the
layer thickness. The fact that convection played no role in the
experiment was checked with Lin' Tszya-tszyao (Ref. 3) and confirmed. The
DH found thus characterized the molecular diffusion Of H2 which was
assumed to diffuse through the slag in the form of protons, and to pans
over from one oxygen atom to another. This transition takes place only if
the distance to the adjacent 0 atom does not exceed 2.65 A, as occurs with
S'02 (d = 2.64 A). DH was practically constant in slag with 56*4% Si02-
DH rises with an increase of CaO and so does the activation energy. Due to

TEXT: To complete thermochemical data of the ternary Na2)-PbO-SiO2 system,
enthalpy and heat capacity values were determined for melts corresponding to sec-
tions PbSiO 3-Na 2S'03' PbS'03_1'a2O-3PbO-6S'O2 and Na~0-2M.3=2_Na2~'L-P The
measurements were mdde on a unit with an adiabatic calorimeter by the ml'od.of
mixing at 4oo - 1,ooo0c, including both the solid and liquid state. The authors
determined melting heats of compounds NaL,0-3fto-68'021 Na2Si~O?Oand Na2~iO
.2PbS'03, and the dissociation constant of the latter for Na2S 3 and PbSi3'
The existence of phase transformation in solid specimens of the system Na2S?6
-PbSi03'at 82OPK was observed. The nature of changes in the melting heats a2
the heat capacities with the composition, leads to the conclusion that there are
atomic orderings in the melts, approaching the structure of Na2S103,2PbSiO and
Na~0-3M'6S'02 compounds, ar-4 that there is a different degree of polymerization

the Interchange energy W is usually considered to be independent. of temperature.
As a result, the excess isobaric potential of mixing 6 F', does, not depend. at all

were produced from pig-iron made by smelting in graphite crucibles
Armco iron, electrolytic manganese and the desired additions of
other elements. 3-5 g charges of the sampl 'es to be investigated
were placed in alundum crucibles and charged into the furnace,
At this temperature all the alloys were paramagnetic. Tho
