ABSTRACT: Measurements were made of 'the e.m.f. in galvanic cells at
1250-14700. Serving as electrodes in the cells were the molten
alloys Fe-P-C, Fe-Gr-C, Fe-Si-C~r-C, Fe-Mn-C, Si-Mn-C,
Fe-S-C, and as the electrolyte a sy-nthetic slag to which oxides
of the element being investigated had been added, It was found
that the e.m.f. changed in accordance with an established law as
a function of the concentration of the alloy coxnponents. From the
v_m.f, data it could be determined how active the 1), Gr, Si, W,

ABSTRACT: A description is given of methods of studying elect rocapillary
phenomena in a metal-slag system at temperatures of 1320-15000.
Such phenomena were discovered in Fe-C ind Fe-P alloys in con-
tact with synthetic slags containing Ca, Si, Al, and Na oxides. It
was found that the surface of the alloys, when the latter were in
contact with the slags, bore a negative electric charge. The results
obtained made it possible to explain why the exchange of CaO for
NaO 2had more of an effect on the interphase balance of the metal
than did the exchange of A1203 for S'OZ. Surface activity on the
part of the Na ions was noted in the systems studied. It was found
that the adsorption of C on the surface of the metal decreased as
the negative potential of the metal increased. An explanation is

ABSTRACT: Methods are described for electrolyzing ferruginous slags in
crucibles of fused magnesia at temperatures of 1300- 1400o. A
drop of molten Au was used as cathode, because Au dissolved
the precipitating Fe, eliminating thereby the possibility of short
zircuits between the electrodes and of metal losses through in-
volvement of the metal in the slag. It was noted that even in the
absence of any current some of the Fe migrated to the Au, which
indicated the presence of Fe in the filag not only in the form of
ions but in a metallic form as well. The current efficiency during
electrolysis went as high as 8Z - 3%. Increat3ing the concentration
of Fa3+ions reduced the current efficiency. This waH accoitnted for
by the fact that aside from tpe discharge of Fe ions, an over-

ABSTRACT: The surface tension (Y of molten oxides was measured by the
value of the maximum pressure in the bubbles. This was the
method used to determine the densities of the silicate melts. The
experiments were carried out at temperatures of 13400- 111000.
The crucibles, capillaries, and tubes were prepared from Fe.
Nz served as the working gas. The surface tension of FeO with a
6. 31o Fe .03 content Was 590 ergs/cm2. When the FezO3and
Si02 contents were increased, the surface tension declined evenly,
reaching 400 ergs/cmz as the Si02 and Fe203 contents reached
30. 5% and 4. 81/o, respectively, The density of FeO at 14000
equaled 4,90 g/cm3. The addition of SiO caused a drop in density

3. 67 g /cm3. The dependence of the specific volume on the com-
position was almost of a straight-line character, which showed
how near an FeO-SiO system comes to being an ideal one When
in MnO-FeO-SiO 2 alfoys SiO2 was substituted for [tic MnO portion
the surface tension declined in a straight-line fashion from 517

23.7%, respectively. In CaO-FeO -SiO alloys of ort ~Osilicate
composition the surface tension was 4le-440 ergs/cm , changing
but little when FeO was introduced in place of CaO. B contrast,
the density in that event declined from 4. 0 to 3. 23 g/cO. The

instead of lime has little effoat on the surface tension
of GaO - 3102 - M90 melts. The results obtained are
explicable by the fact that with Increasing elootro-
negative character of the element (Ca, A10 Si) the
proportion of the homopolar por"t-ion of its bond with
oxygen increases. The'method proj~nsed by AppenlO for

ABSTRACT: The fulfilment of the Faraday law is one of the experiment-
al proofs that the interaction between the metals and the
slags is electro-chemical (1). Study of the electrolysis of
slags rich in MnO and PeO is of particular interest
since several authors (2 and 3) express the view that such
slags are semi-conductors. In an earlier paper by two of
the authors of this article (4) it was shown that cathodic
precipitation of iron is possible not only fron FeO-SiO
slags but also from FeO-Fe 0 melts and the assumption was
expressed that the deviation Prom the Faraday law may be due
to the recharging of the ions of the iron. For judging the
behaviour of manganese containing slags during electrolysis
Card 1/4 the authors considered it useful to investigate the cathodic
rocess; the data published by F. Sauerwald and G. Neuendorf
) are not detailed enough. The authors of this paper

causes which determine the degree of utilisation of the
current. For the experiments the authors used a cell of the
same design as was described earlier (4) for studying the
electrolysis of ferrous slags; it consists of a cylinder of
molten magnesia into which three compartments are drilled,
Fig.11 p.86. The quantity of electricity flow was measured
by mean of a copper Coulomb meter, the temperature was
measured by platinum/platinum-rhodium thermocouple and the
sequence of experiments was similar to the one described in
an earlier paper by the authors (4).At the temperatures under
consideration (1250-1400 C) liquid manganese could be used
~s a cathode but it was found preferable to use silver
instead. The results of the electrolysis of MnO-SiO 2 slags
at 1250-1350 C are summarised in Table 19 p.87 for 22 tests,
the results of the electrolysis of MnO;SiO -CaO slags with
silver cathodes at 1250 to 1300 C (expe ime&Nos.23-30) and
of MnO-FeO-SiO 2 slags at 1300 C (experiment No.31) and of the

(Table 2). Data on the utilisation of the current in the case
of anodic dissolution of the manganese in slags corit6ining
68% MnO and 32% SiO at 1260 to 1280 C are given in Table 3,
p.90. It has been ix;erimentally established that under
certain conditions of electrolysis of molten manganese
containing slags the Faraday law is fulfiLed on the -cathode
as well as on thq anode. It Was found chat reduction of
the i0l and Fe2+ ions to Mnc+ and Fec+ ones is"the
fundamental cause reducing the cathodic yieldin respect
of the current,of manganese. An increased ratio of the
height to the diameter in the c~thodic PSJ~tB Blows down to
convection diffusion of the h1n + and FO+ ions and brinss
about a better utilisation of the current. Calcium oxide
additions also have a favourable influence on the current
utilisation of manganese slags and this is attributed to an
increase in the viscosity of the slag which slows down
convective diffusion of the manganese ions. It was found
that for low current densities of manganese slags,containing
Card3/4 only a slight percentage of iron oxideB, iron will precipitate
preferentially at the cathode and at higher current densities
Mn will precipitate preferentially. The existence was

which is similar to the one established earlier for ferrous
slags. It was found that the dissolution of silver in the
studied melts is not related to the degree of oxidation of
the slag but is directly proportional to the slag volume
and the assumption is expressed that silver passes into the
slag not in the ionic but in the atomic or the colloidal
form.

have proved experimentally that the reversible hydrogen
electrode can be materialised relatively simply for
molten slags which do not contain easily reducible
oxides. New experimental data confirm. that solid
magnesium oxide which is in contact with the liquid slag
operates as a sort of oxygen electrode. The measurements
have shown that the activity of the water dissolved in
the slag is proportional to the s('juare root of the activity
of the calcium oxide; this is in ELgreement with the
assumption that the hydrogen in the slag is present in the
form of hydroxyl anions. The relation between the e.m.f.

considering the negative magnitude of the e.m.f. as a

A-9STRACT: This article is a summary of the latest results obtained by research
work- in the filed of silicate melts. The bond metal-oxygen in sil-i=
cate melts is differently iogenousq according to the metal. This is
shwon by two diagrams on the basis of the dependence of surfa':e ten-
sion, on the ratio between charge number and atamic radias -and the
dependence of the isobaric activation potential of --lectr-;c cow-bic.-

PERIODICAL: Tr. Ural'skogo politekhn. in-ta, 1957, Nr 67, pp 5-Z7
ABSTRACT: A review is presented of experimental investigations into
the electrical conductivity, the electrolysis, and the transference
numbers of fused oxides, and the nature of their conductivity is
examined. Studies on the mensuration of eirif and polarization
in silicate rnelts provide the basis for a discussion of their
structure, the energy of reactions between particles, and the
structure of the interface between the ME and the slag. The re-
sults of experiments in the study of the kinetics of desulfuriza-
tion, of dephosphorization, and of the silicon- reduction process
by means of radioactive isotopes are given, and an analysis
thereof in the light of ion theory is given.

ABSTRACT: Measurement is made of the charging currents on an incip-
ient metal surface in contact with slag, the cases being Fe-C
and Mn-C alloys saturated with C and slag of the following con-
tent: CaO 3976, Si02 4174, and A1203 Z0% (1), and CaO Z57a,
Sio? 63016, and A1203 121% (11,j. The experiments were conducted
at temperatures of -15000C in fused-MgO crucibles. It is
established that in both cases the metal surface in contact with
the slag has_a negative charge. In the case of Fe-C ts magni-
tude is 3- 10 6, while in the case of Mn-C it is 6- 10-~ coulomb/

PERIODICAL: Tr. Ural'skogo politekhn. in-ta, 1957, Nr 72, pp 246-251
ABSTRACT: Radioisotope Fe59 is used to investigate the kinetics of the
SiO2+Z[Fej =2(FeO) +[ Sil reaction. The Fe59 was introduced
into molten technical Fe, which was kept in a quartz crucible
under an N2 atmosphere within a carbon-resistance furnace,
beneath slags made of SiO2, Al,Z03, CaO, MgO, and BaO. The
rate of reduction of the Si by motten Fe is determined by the
rate at which the Fe 5t) goes into the slag. Roijults of exy)eri-
ments with slag containing 61.256 SiO2, 17.301D A1203, 19.43%
CaO at 1580, 1620, and 16700C show the energy of activation
of the process to be 64, 000 cal/mole, A change in the height
of the slag layer frorn 8 to Z5 min does not affect the process
rate. These data support the conclusion that the limiting factor
in the process of Si reduction is not the diffusion of Fe ions in

The Kinetics of the Reduction of Silicon by Molten Iron
Experiments conducted with slags consisting of 32. ljo MgO and 66.4jo SiOZ,
34.6% CaO and 64.18% SiOZ, 37.7Z76 BaO and 59. 1116 SiO2 at 15800 showed
that replacement of MgO by CaO diminishes the rate of S i reduction by 321~'O.
while when BaO is used it is reduced by more than 901o. Theije facts have
clarified the differing influence of the MgZ+ , C;L?+ , and BZ+ cations on the
strength of the bond between Si and 0 in the slag.

ABSTRACT: A description is offered of the results of experiments in
1948-1952 in the electrochemical refining and alloying of
metals. The laboratory experiments were run in a resistance
furnace with a Silit electrode and in a 50-kg high-frequcncy
furnace, Electrochemical refining of metal proved feasible.
The application of an external electrical field to a metal- slag
system makes it possible to regulate the speed and complete-
ness of transfer of S from the metal into the slag. Pilot-plant
experiments at the Verkh-Isetsk Plant employed a D-C gener-
ator (1000 amps, IZO v). The metal was poured into a 300-kg
ladle. The results of the industrial experiments showed that

sulfur from the steel proceeds with considerably greater efficiency than
without electrolysis. Depending upon the initial composition of the metal
and the slag and upon the quantity thereof, the S content dirninished by
0.020-0-.0457o during the first 10 min. Simultaneously with the removal of S
from the metal, an increase in Si content was observed. Current efficiency
was from 20 to 967o. The experiments demonatrated the deoirability of
further development of the method and of its introduction into industrial
practice.

ABSTRACT: The electric conductivity is investivated of iron-
phosphorous slags, the electrolysis and also the cathode
and anode polarisations. The specific electric
conductivity was studied of Fe-P slaS~s containing 1965
and 28.8% P 0 in the temperature range 780 to 1250 C.
It was esta~l?shed that an increase in the Fe 207 cont-ent
leads to an increase of the electric conductiMy and to
a decrease of the activation enerGy of the studiad alloys.
It was found that substitution of FeO by CaO reduces
the conductivity and increases the activation ener~~y.

ABSTRACT: In the paper (Ref 1) it is assumed that by substituting calcium
oxide by barium oxide In the slag it should be possible to elimi-
nate phosphorus from the metal to a higher extent. In oider to
obtain direct confirmations by tests the equilibrium of the phos-
phorus between iron and alegs ocintaining barium oxide was analyzed.
The experimental method used hafi already been doooribed in the
paper (Ref 4). Technically pure iron was employed for the tests.
The slags consisted of synthetic alloys of oxides of calcium, barLum,
silicon, magnesium and iron. The concentration of BaO varied 'be-
tween 5 and 35 %. The tests showed an increaBe of the distribution
ixidwx of phosphorus within the composition range investigated, like
the ratio of the radioactivities of the slag to those of the metal,
with the rising content of calcium oxide as well as of barium oxide.

consisting of iron oxide. The distribution factor,5, however, are
not remarkable in such a case. The presence of Fe ;e+ ions in the
slag permits the transition of phosphorus whilst the ions of barium
contri.bute to complete the transition. Tho introduction cf the
cation of Si4+ or of A13+ into the slag will bind the 0 2- ions still
more, and reduce the distribution factor of phosphorus. It is shown
how the degree of dephosphorization increases with the basicity of
the slag at a constant ratio BaO/FeO. There are 2 figures, 3 tables,

tube. The conductivity measurements were made over
temperature ranges covering both liquid and solid states.
The melts were held in corundum crucibles. The resis-
tance was determined by means of a bridge fed with a
100 c.p.s. current, using a cathode ray osaillograph to
indicate the balance conditions. Platinum wire
electrodes were employed for immersion into the oxide
mixtures. The accuracy of the measurements was 10 to 15%.
The experimental mixtures were heated to the maximum
temperature and held at that temperature for 15 to 20
minutes, after which the melt was cooled and reheated.
The most reliable conductivity measurements were obtained
during the second heating cycle, and only these values
arc discussed in the paper. Chemical analysis after the
final cooling showed that dissociation had occurred to a
high degree, thus explaining the vigorous gas evolution
Card 2/7 observed during melting. The composition containing.15%

Card 3/7 but according to Martinet (Ref 3) and Grunewald (Ref 4)
it can be att*-,*ib-ated to the admixture mechanism of

of RFe0 as a decomposition product was believed to explain
why many of the investigated compositions did not display
this conductivity decrease; (c) the conductivity

maximum, whose magnitude increased with temperature, is
probably due to decomposition of GuO which brings about
an Increased concentration of' the current carriers. The
conductivity isotherms of the ternary and quaternary
systems are shown on Pigs 5 and 6 respectively: in these
cases, no decrease In the conductivity with rise of
temperature was observed. The experimental findings
indicated that all compositions of the two studied quasi-
binary systems behave as semi-conductors both in the

semiconductor mechanism to the ion mechanism in the
systems begins with unequal Me:O concentrations. In al;oys
of V205 with CaO it begins at 23,4 % CaO, in the V205_MgO-
system at 27,7 /v MO and with V2O,-PbO at 71 ~.. PbO. In all
cases the transition-begin co3rree~onds with tho firot
chemical compound in the respective system. Such a regularity
points out the important part of the short range order in the
atomic distribution for the realization of the semiconductor
electric conductivity in alloys. The character of the
polytherms for the electric conductivity shows that in the
V205-PbO$ V20 5-CaO and V205-MgO alloys the semiconductor
mechanism passes over to an ion mechanism with compounds
which correspond to the chemical compounds with the least
second component (MeO). The regularity determined proves the
opinion of Ioffe.

TITLE: Cathode Polarization in the Separation of Silicon, Iron and

ABSTRACT: The cathode polarization in CaO - A120 3 - 14,-0 melts trith
small additions of SiO 2t Fe20 + FeO- as well as with Ila 0
for comparative purposes wa nvestigated. The measuremenis
were carried out at 1400-1500 C according to the commtitator
method (Reference 2). The cathode polarization ~L in the se-
paration of sodium, silicon and iron from the oxide melts
was measured. It was found that the quantity I does not de-
pend on the electrode material, that it decreases in mixina
and that it follows tho oquation for the concentration pola-
rization. It io shown that in the cnult)5 invontigatod tbo pola-
Card 1/2 rization is dependent on the slowed down diffu3ion of the

sodium ion and of the 3- and 2--valent iron ions in the elec-
trolyte. Summarizing the authors state that the concentration
polarization in oxide melts is widely spread. This is con-
nected with the small values of the diffusion coefficients,
as the diffusion in them is not greater than in aqueous so-
lution.3. The shape of the CUTVe;3, the mutual position of the
element separation potentials wid the observed proportionali-
ty of the boundary amperagee with the concentrations permit
to speak of the possibility of a high temperature polaro-
graphy in oxide melts. There are 4 figures, and 10 references,
8 of which are Soviet.
