that by the increase of the electric field of the ions the
increase of their polarizability is decreased. The iodides
of copper, zinc, lead and cadmium are =entioned as examples
for the case that no polarization increase and thus aliio no
change of tho thormodynamlo proportion talcon place. After
giving a detailed consideration and explanation of the re-
action of the metals mentioned in the table the authors say
that among the mentioned salts the strongest Belective effect
on chloride compounds of nickel, cobalt, copper and iron was
observed with alkali metal chlorides, with the extremely
small decrease of potential of nickel chloride being used
for the purification of nickel-sulfur alloys. There are 1

was observed that the W varies, which fact was explained
by the oxidation of Mn to mn+3; the experiments were cor-

ABSTRACT: The present investigations are intended to solve the problem
whether in a flow of silicate an orientation of the anions
takes place having a different resistance along and across the
direction of flowt The experiments were carried out by means
of melts of the system Na 20-SiO 2 in an apparatus the diagram
and the description of which are given. The flow rate was
not always the same, it never surpassed, however, a Reynoltd
number of 20, with the transition from an accelerated flow to
a normal flow taking place according to Gagen-Puazeyl in the
initial section of I ca length* The representation of the
electric scheme as well as a description of the operation method
Card 1 are given. The results obtained show a clear anisotropy of the

electroconductivity, with a decrease of the resistance being
observed in the direction aling the flowt and an increase of
it in the cross dirootions This in axplained by a oomplar
atructure of tho vilioon oxide anion, and it in assumed that
an orientation of chain- or lamella-type silicon oxide anions
in the direction of flow is present. It was found that the
observations made agree with those by Bockris and Lowe (Bokris
and Love)(Ref 12), and that they contradict those by Bask (Bok)
(Ref 13). In the explanations of the results obtained, referring
to the periodicity of the above anisotropy by thp change of
the composition of the silicate the authors give data obtained
by N. V. Belov (Ref 15). There are I figure and 15 references,

ABSTRACT: The phenomenon of cathodic polarization in liquid slags
already observed (Refs 2,3,4) is in the present case
investigated with melts of CaO-MgO-A1 203-B203 (with small
TiO2 additions). The construction of the electrolyzer
according to Piontelli (Ref 7) turned out to be insufficient,
and the direct method was not employed because the
Lugin-Gaber capillaries are difficult to produce. The cathode
otential. was measured according to the commutator method
ef 2) with an electrolyzer being usedl a diagram of the
N
electrolyzer is given. The determinations were carried out
at 14000 with Cu - Ti, Fe - P - Ti and Iff-cathodes. A slow
diffusion of the TO+-ions was observed. The absence of
abrupt polarization drops also points to a diffusion character.

TITLE: The Application of Radioactive Indicators to the Study of
Diffusion In Liquid Slags
PMODICAL: Tr. Urallsk. politekhn. In-ta, 1958, Nr 73, PP 57 - 73
ABSTRACT: To elucidate the structure of liquid phases, diffusion (D) of
Ca and S separately was investigated and that of either Ca ard P
or Fe and Ca simultaneously was also studied. Liquid blast-
furnace slag of the composition (in %)-. CaO 40 Al 20.3 20,
810 40 served as medium. The experiments were ~arrled out in
the isothermal zone of the furnace with a carbon resistance at
a temperature of 1,300 - 1,6000C. The method of "labeled atoms"
was employed for revealing the results of D. p32 was introduced
into slag in the form of tricalcium. phosphate, S35 In the forin of
sulfides, Ca45 and Fe59 In the form of oxides. Slag was molten
in a crucible (C) and kept for 15 - 20 minutes, then a little

investigated, was preliminarily heated and carefully introduced onto the
surface of the melt. The experiment lasts from 1 to 9-hours. It was
established that in liquid slags of the CaO-A129 S102 system the mass
transfer of Ca, P and S in a graphite C takes pla-ce at temperatures of
1,300 - i,6ooOC at the expense of surface D. The material of C Is badly
wetted by slag, and the boundary- melt-C is a passageway for diMising
perticles. In the case of introducing the sulfur isotope ( - 1%) into
slag the wettability of C increases and the D rate of sulftu, decreases
3 - 4 times. In the case of using C made of A1~03 the wettability increases
and the D rate of Ca, S and P in this case was less than In a graphite C.-
The investigation of the simultaneous mass transfer of P and Ca, as well as
of Ca and Fe, showed that their conditional diffusion coefficients are values
of one order of magnitude, P and Fe are triurisferred somewhat more rapidly-
than Ca.

ABSTRACT: At temperatures of 1370 - 1500 OC the authors noticed a shift
of the drops of Cup Ilip Mn, Ag, Ili S2 to a certain electrode

the authors could observe the ainultaneous motion of a Great

cases where liquid electrodes 01, Ili 3 2 3upplied from graphite

all observed in the case of solidified metal drops and pieces of
solid maGneniun o;,.ide. The results of the experiments in an
oxidizine atmosphere (air) are compiled in a table. The same

ABSTRACT: The present paper gives the results obtained by an inveBtiga -
tion carried out by the authors of the use of the electro-
capillary motion of liquid metal drops for the purpose of ex-
tracting sulphide inclusions from molten slags. Experiments
were carried out at a temperature of -14000 in boats of
corundum or porcelain, which were filled with molten factory
slags of the following composition (in %): CaO 15; A1203 10;
S102 43; Fe 20; '14gO 10; Ni 0.1-0.2; Co 0.02; and S 0.15-0.2.
A large part of nickel and cobalt was contained in these slags
in form of matte inclusions of from 10-4 to 0.2 mm. Carbor-
undum rods were used as current conveyers. In preliminary ex-
periments, matte drops of large radius (r - 0.9 to 1.3 mm)
were dipped into slags, and nfter 2 - 10 minutes a constant
Card 1/4 electric field with a field strength of from 5 to 7 v/cm was

connected. The cell was then quickly oooled, and the path
covered by the drops was determined. The inclusions move with
velocities of u = (7 + 10)10-3 cm/sec in the direction of the
cathode, and this2corresponds to a mobility of v = u/Er n
= (1-0 + 1.5).10- cm/sec.v. The authors also investigated the
influence exercised by the composition of the slags. The
results obtained with Ni3S2 drops in iron-less slags of various
compositions are given in a table; they show that the mobility
of the drops is inversely proportional to the viscosity it
of the slags. The data obtained for different iron oxide con-
tents in the slags are given in the sinond table. Tile charge

of the drops in spite of the fact that their positive charge
increases and the viscosity of the slags is reduced. Concep-
tions on an ideally polarizable drop are absolutely out of
place in the case under investigation. The eqiiation deter-
mining mobility contains a depolarization coefficient. The
reduction of drop polarizability is probably the main reason
for the reduction of its mobility in the slags which contain
iron oxides. An additional proof of the correctpess of what
haa been just said is furnished by the results obtained by
experiments carried out with constant FoO concentrntion (2'5
and a variable ratio between CaO and S102 contents. Also in
this case the mobility of drops hardly depends at all on the
viscosity of the slags. The experiments discussed fully con-
firm the possibility of extracting valuable sulphide in-
clusions from molten slags by means of electrocapillary

TITLE- On the Moot Simple Corrections to the Equations for Re;~ular
Solutions (0 prosteyshikh popravkakh k formulam regulyarnykh

PERIODICAL: Nauchnyye doklady vyashey shkoly. Metallurgiya, 1959, Nr 1,
PP 5-10 (USSR)
ABSTRACT: In this paper an attempt is made to find simple extensions of
the formulae from the theory of regular solutions, which would
permit to extend the range of applicability of thene formulas
considerably, At first the influence of temperature is investi-
gated. Formulae (20), (30), (40), and (50) are obtained
for the heat of mixture & H9 for the excess entropy 4 S'v and
the excess isobaric potential 6z'. From these formulas it
can be seen that.A z' is linearly dependent upon temperature,
and that the relationship between,& H,,A zi, A S' and flee
composition of the solution is also linear. Subsequently the
consideration of the deviation from the additivity of the
bindings is investigated. Formula (112) for the energy of
mixture,a E is written down fox one mole of solution ac-
Card 1/4 cording to the theory of regular solutions. In this instance

Regular Solutions
it is assumed that the atoms interact by means of short range
order forces. It is further assumed that the atoms are in a
state of statistical disorder and that in the calculation of
the energy of mixture the rule concerning the additivity of
bonds is applicable. Attempts, are made to estimate the influ-
ence of small deviations front the rule of mixture for indi.-
vidual bonds. Formula (4,2) in derived. In this formula,
denotes similar as for regular solutions the "enerLry of
mutual exchange", whereas q denotes the deviation from the
additivity of the binding energy between different atoms:
Assuming that the entropy of mixture is identical with that
of an ideal solution, formula (5p2) for A zf is written down.
This formula specifies satisfactorily the thermodynamic
charaoteriBtics of the isothermal lines of a number of
silicate melts and of sulfide and metallic solutions (Ref 10)~
which are characterized not only by asymmetric curves for
,~~zl, but also by deviations with change of sign. This
formula doesp however, not express the dependence of-,A z'
upon temperature. It is assumed that temperature takes a linear
Card 2/4 course and thus formulas (6,2), (T,2), (8,2), (9,2); and (10;2)

Regular Solutions
are obtained. In order to elucidate the practical use of
these formulas, the three systems tin-thalliun, tin-zinc, and
sodium-cadmium are investigated. The excess isobaric potential
for the first system follows a linear relationship, that of
the second is described by an asymmetric curve, the last
system is characterized by deviations from the ideal solution
with change of sign. Q and q were determined with the help of
activities of one component of two mixtures found experimmen-
tally, whereas for the coefficient k (a constant which depends
upon the nature of the constituents of the mixture) the
experimental data for 6 z' at different temperatures were used.
From a comparison of the experimental and the theoretical
data follows that the system tin-thallium is an example of a
solution, for which A S' differs noticeably from zero,
although the isothermal lines of the activities follow the
rules of regular solutions. The system tin-zinc exhibits a
close agreement betwe4n the activities of the components and
those of the enthalpy of mixture, which were computed according
to the formulas (4,3) and (8,3), presented in this paper, and
Card 3/4 the experimental data. For the system sodium-cadmium the

computed values for A z' coincide with the experimental
values, whereas considerable deviations in the values appear
for 6 H. There are 3 figures, 2 tables, and 13 references,
7 of which are Soviet.

ABSTRACT: The specific heat in the PbO-SiO 2 melts was measured in the
temperature interval of 550 0- 9600 in solid and liquid state.
The average molar specific heat and eathalpy for melts of
different compositions are given in tables 1 and 2. The
dependence of the melting heal; (L) and enthalpy (& 112 T8)

on the composition of the samples of the system was investigated
and is given in figure 1. It is concluded from the results
that stable compounds with tho group Pb-O-Si exist in the
melts. The experimentally meanured c -values are higher than
the additively detected ones. The results concerning the
enthalpy, of the specific- and melting heats confirm the fact

combinatlon of' the two electrochemical stages, in
one of which the substances Lrain electrons, and In
the other they lose them. Therefore, in the atudy
of these reactions a method of polarization can be
used. The authors selected the polarization by
alternating current. This method permits a simultaneous
determination of both kinetic characteria`C;Ics of the
stage: the constant of the reaction rate and-the coef-
ficlent of diffusion of ion In the slag. The essence
of this method, offered by B. V. Er5hler and co-au-
thors, is that a low amperage alternating current is
passed through a cell consisting, for instance, of
two liquid metal electrodes and the molten slag which
connects them. The resistance of the cell Is balanced
by an alternating current bridge, by ohmic resistance

ABSTRACT: Measurements of the emf E of a cell were used for
determining the standard changes 0of potential-AZ', of
entropy /AS* and of enthalpy 4H . By introducing a
accond oxide in the electrolyte, the activity of the
components and the deviation of the Lixermodynamic functions
from idea values can be calculated. The ulag sysLetzis

for the activity of PbO with the previous results by other
workers. The present results are similar to those of
Richardson and Webb (Ref 7). The negative deviations from
ideal solution indicate the formation of Pb..O-Si, the
stability of which increases with decreasing, temperature.
The thermodynamic. functions for tho PbO--SI.04,, system are
given in Table 3 and Fig 3. Tho results confirm the
formation of Pb-O-Si, with a decrease in potential and
entropy and evolution of heat. The resuLtm of rAudies of
the PbO-V205 system are given in Fig 2. This system shows
greater negative deviations from the ideal state. The
thermodynamic functions are given in Table 3 and Fig 3.
These confirm the formation of Pb--O-V. Results for the
system PbO-SiO2-'V205 are given in Table 4. Negative
deviations are again observed. Results confirm that the
bond in Pb-O-V is stronger than that in Pb-.O-Si. The
thermodynamic characteristics of PbO, in the ternary system
are given in Table 5. There are 3 figures, 5 tables and

The points of the initial sections of the polarization curves
are in the coordinate system ~f lg(1- 1 ) actually on a straight
in
(Fig 1) with an angular coefficient equal to n W 5. Consequent-
ly the reaction V 5+ + 5e a V takes place on the cathode (3).
The further course of the polarization aurve for the melt con-
taining SiO 2 shows that Si is discharged. Thus, under the con-
ditions chosen a separate deposition,of V and Si is possible.
This was examined on melts'with small additions of SiO 2 and V20 5
(Fig 2). In the aforementioned coordinate system two straight
lines result corresponding to reaction (3) and reaction
Si4+ + 4e - Si (4). At an increasing concentration of V 205
(UP to 35%) a considerable polarization occurs (Fig 3) which
diaobeys equation (2). It iu explainod by an nowimul4tion of tho

n decreased however from 0.3 to 0.2 though the concentration
oi P 205 was constant. The mobility oi the Ca2+-ions was inves-
tigated in corundum tubes by meaiw of tagged atoms. The diffusion
was measured under and without the action of electric current
(Fig 3) and a noticeable electrolytic mobility of the phouphorue
in CaO-P 205 melts was determined,, The oloctrio transport in those
melts is not only done by 11'a-ionsp but also by P-iona,
whereby the latter do not migrato as complex anions but as
cations. Though the ionic charge of Ca and of P is almost equal
and the radius of the P-ion is smaller, the mobility of the
P-ion is lower being retarded by the stronger P-0 linkage. In
the diffusion however, the phosphorus migrates as cation as
well as with the oxygen anions, similar to diffusion of ionic
pairs in NaCl-melts. There are 3 figures, 2 tables, and 19
references, 13 of which are Soviet.

TITLE: Magnetic bilit of Antimony-Palladium Melts
PERIODICAL: Fizika metallov i metallovedeniye, 1960, Vol.10, No.5,
pp.798-800
TEXT. In recent years, magnetic analysis has been widely used in
chemical studies. This method is one of the few which can be used
to obtain direct information on the structure of liquid metal
systems. The present paper reports measurements of the magnetic
suspectibility of antimony-palladlum melts, using the Faraday
method. The force on the specimens was measured with the aid of
an analytical balance, the balancing force being produced by a
permanent magnet and a compensating solenoid. The specimens were
placed in a heater consisting of two coaxial quartz tubes.
A bi:Cilar nichrome heater was wound on one of the tubes, The
temperature was measured by a thermocouple. All the measurements
were carried out at atmospheric pressure in an argon atmosphere.
Sponge palladium and chemically pure antimony were investigated.
At room temp 9rature the magnetic susceptibility of antimony was
- 0.34 x 10- while the susceptibility of palladium was

22.8 x 10-6. These figures differ from published data,
indicating that the materials employed contained some unknown
impurities. The palladium antimony alloys (44% Sb and 56% Pd)
were prepared in an argon atmosphere at 9000C. 1.765 g of the
material thus obtained was placed in a quartz ampoule, the
susceptibility of the quartz ampoule being compensated for by an
identical empty ampoul-e. The working space was then evacuated and
filled with argon and the specimen was heated to 8500C. After the
measurements had been carried out, the temperature was reduced,
the ampoule was weighed and the loss of antiniony from the alloy was
determined, It was usually found to be between 0,005 and 0.02% of
the total amount of material, A known amount of antimony was then
added and the experiment was repeated. The results obtained are
shown in the figure and table on P-799. They show that
palladium -antimony alloys have a weak diamagnetism at 8500C,
while at room temperature they re relatively strong paramagnetics
(susceptibility between 2 x 10-9 and 9 x 10- ). As can be seen
from the figure, the susceptibility versus concentration curve has
Card 2/3

S/126/6oXV/OO5/030/030

Magnetic Susceptibility of Antimony-Palladium Melts
a minimum of 54% Sb. This can apparently be explained by the
formation of a valence bond between the d-electrons of the
palladium atoms and the p-electrons of the antimony atoms. The
above concentration of 511%, Sb corresponds to) the oompound PdSb.
The present measurements thus indicate that in palladium- antimony
melts" there are ordered structures corresponding to the compound
PdSb. There are 1 figure, 1 table and 7 references: 2 Soviet and
5 Non-Soviet (one of which is translated in-to Russian).

in which the silicate to be investigated is melted. A tungsten cathode is
introduced into the melt, which is surrounded by a cci-nindum shell dcwn
to the lower end, and further also two corundum tubes, whose diameters
are accurately measured with an M "P-IM MR-IM) microsco.ne, In "he twc
tubes two tungsten rods are dipped into the melt, one tungsten rod serving
as an anode. Onto the immersed points of the two tungsten rods, radic-

current is caused to pass through the rod oerving as an anode. Trunsfer
of the isotope from the tungsten rod not connected with the circult is
thus carried out only by natural diffusion and ocnvection. The duraticn

TEXT: The authors give a critical survey of investigations
of thermodynamic properties of alloys (mainly binary metallic)
in relation to the corresponding phase diagrams. Deviations
of solution from ideality form the major part of the survey.
For systems with continuous solid solution deviations are
usually slightly negative or zero. An example of the rare
system where positive deviation in the liquid accompanies
complete miscibility in the solid could be Au-Ni but the
authors doubt the evidence (Refs. 2, 3). Most such systems
obey regular-solution laws. Simple eutectic alloys generally
show positive deviation; those that show a negative deviation,
such as Bi-Pb, are specially interesting. Negative deviations

also occur when unstable compounds, decomposing below the
melting point, are formed. Especially large negative
deviations occur in alloys of iron with nonmetallics. E.m.f.
measurements (Ref. 5) indicate the existence of stable FeSi.
These results are in line with those of other methods
(Refs. 6, 7, 8, 9). The e.m.f. method has also been used
(Ref. 10) for carbon-saturated ferro-alloys: Fe2p was
detected in Fe-P-C (Ref. 12). Positive deviations are suggested
if there is an immiscibility "dome" on the phase diagram;
other links between e.m.f. results and phase diagrams have
been reported (Refs. 16, 17). The submicro heterogeneity of
eutectoid liquid alloys is suggested by X-ray (Ref. 18),
centrifuging (Ref. 19) and thermal (Refs. 20-22) experiments.
The authors doubt the valdity of Bartenev's views (Ref. 23)

TEXT: T he electrochemical extraction of V from dumped or conversion
blast furnace slaq containing up to 2W. V 205 and up to 40% Pao is
described. The cathodic current yield of V in relation to Dc, the furnaco
atmosphere, the composition of the slag and metal and the temperature is
investigated. In oxidizing atmospheres the cathodic current is much lower
than in reducing atmospheres, since in the first case the V is in the
form of V 2050 Variation between I and 2- 5 a/(,m2 in D. may be accompanied
by a possible variation between 5 and 25c/lo in -the initial V content. The
metal bath of the furnace can be used as the oathode. [Abstracterts note:

the rate of transfer of ~In is somewhat lower than for Fe.
For technically pure Fe And Nin the reaction occurs under kineLic
rate control conditions 1o3 timos faster than for alloys with
C, Si and P; evidently these components, because of inter-phase
activity, isolate the surface atoms of the metals.
