In cooling of gases from furnaces for smelting of
SI alloys, silicon oxides are condensed with the
formation of a liquid phase contg up to 85% of SiO-
Oxidation of Si and its alloy proceeds gradu&Uy
vith inter-mediate formation of SiO. The interpbase
tension at the boundary of Fe-Si alloys with slag
fusions was measured. Si substantially lowers the
USSR/Cbemistry - Silicon (Contd) Jun 52
surface energy of the alloy. Substitution of Fe
by Cr, i.e., conversion of ferrosilicon to forro-
silicon chromium, is accompanied by a very slight
rise of the interphase tension. The very low in-
terphase tension at the boundary of the silicon-
silicate melt is explained by the forsation. of SiO,
vhich lowers the energy differential between the
phases in contact and favors of unification their
structurally similar elements.

TITLE: Reduction of Chromium Oxide With Carbon (Vosstanovleziiye

PERIODICAL: Tr. Urallskogo politekhn. in-ta 1957, Nr 72, pp 179-191
ABSTRACT: The applicability of the two-stage theory (reduction with CO
gas, regeneration of CO with carbon) to high- temperature pro-
cesses of direct reduction was investigated. The process of
direct reduction of CrZ03 with carbon at a molecular propor-
tion Cr?03',C ~ 1:4.5 was studied by means of the observation
of the loss of weight of a specimen with a simultaneous inspec-
tion of the composition of the products formed by the reaction.
The gaseous phase consisted of practically pure CO. The pro-
cess of reduction was studied in vacuo as well as with an ac-
cumulation of CO in the system. A sharply defined incubation
period was discovered, the duration of which increases with a
lowering of the temperature, also a period of increase in rate

direct reduction of Cr?_03. At low temperatures an inc rease in pressure re-
tards somewhat the interaction and at elevated temperatures it noticeably
accelerates the process. It is shown thdt the substitution of inetallargical
coke for graphite leads to a sharp der-re.~se m the rate of reduction. Influ-
ence of salts of alkali metals was studied. n), pi,,eilce of K)CO3 and
Na2C03 increase~considerably the ratc. of r(-dLl( 0011, the action W . elther
carbonate being about the same. The introduction of in activator in theforin
of a dry salt and the impregnation of the graphitt: with in aqueous solution
show a similar effect. This 'leads to the conclusion that at a high tempera-
ture dry salts impregnate the C with the- 'r vapors and activate it. The acti-
vating effect of the salts on the rate of gasificatior of C with carbon dioxide
is corroborated by a direct experiment at 1000 ~; ~. According to the conclu-
sions of the authors, in the primary period of reduction of Cr?03 by C the
limiting stage of the process is the act of c rys tit Ilochernical transformation
of the oxide into the metal. During that period the energ,
.y of activation at-
tains 140,000 cal/mol. During a definite stage of the reduction, when the
formation of a reaction zone is completed, the kinetic complications, in re-
lation to the regrouping of the lattice, decrease,and to a considerable extent
the speed of the process begins to be determined by the speed of gasification

of the rate of reduction to the pressure of the gaseous phase, a decrease of
the energy of activation of almost 5016, and others).

PERIODICAL: Tr. Ural'skogo politekhn, in-ta, 1957, Nr 7Z, pp 19Z-195
ABSTRACT: By experimental reduction of ZnO with solid C in a vacuum
it was demonstrated that the rate of reduction has no relation
to the compression pressure in the range of 0 to 600 kg/cmz.
This emphasizes the important role of the gaseous phase and
the two-stage character of the process of direct reduction. Upon
changing the pressure of the gaseous phase it was discovered
that the rate of reduction of ZnO in a partial vacuurn is some-
what higher than in a high vacuum. Upon accumulation of re-
action products a considerable retardation of the process is ob-
served. Such an extreme dependence of the rate of the process
upon pressure is explained by an acceleration of the reaction

ABSTRACT- A study of oxidation of Fe-Cr alloys the Cr content of which
varied from 0 to 19.276 by S vapors at a vapor~pressure of 50
rnm I-Ig at temperatures 500-8000C. It is shown that the rate of
corrosion diminishes rapidly with a lowering of temperature
and increase of Cr content in the alloy. Small additions of Cr
(3-4%) lower the average rate of oxidation by one-third to one-
half- an addition of IZ- 17% increases corrosion resistance

rnent of the electric properties of external and internal layers
of sulfide scale have revealed experimentally the analogy of

ABSTRACT The corrosion of Fe-Mn-alloys (with contents of Mn from
0.01 to 15.3Z016) in vapors of S at 500-8000C has been examined.
It was revealed that an increase of Mn to 1576 lowers the rate
of corrosion of alloys in the 500-800' interval in an approxi-
mately linear proportion. The chemical and X-ray analysis of
layers of scale showed that with low concentrations of Mn in the
alloy, the Mn distributes itself almost uniformly through the
entire thickness of the scale. With 6-9% of Mn in the original
alloy an accumulation of Mn in the form of MnS takes place in
the interior layer of the scale. In high-manganese ( 151/6) alloys
the quantities of FeS and MnS contained in the interior layer
are commensurate; the comparatively small inhibiting effect
