TITLE: Reduction of Manganese Verrite by Hydrogen and Graphite
PERIODICAL: Doklady Akademii nauk SSSR9 196o, Vol- 132, Noo 5s,
pp. 1074 - 1077
TEXTz The authors carried out the above reduction by hydrogen in a
closed apparatus with gas circulation. The reduction rate of ferrite
rises as the reduction progressee and reaches a maximum at about 30-40%
oxygen removal (Figo 1). The reduction then slows down and comes prac-
tically to a halt after removal of 75% 0 According to X-ray-struc-
.F 2*
The use of graphite powder in a vacuum of about 10-2 mm caused the re-
duction rate to decrease with progressing process (Fig. 2). The kinetic,
curve shows a clear minimum at about 25% reduction. The reduction then
accelerates a little, only to sink to nil towards the end of the proces 11

Graphite completely reduces manganoferrite at 19000 ,The Spinell phase
can only be proved for up to 2C% reduction. Possible phases here are
ferrous oxide, manganous oxide, or their solid solutions. No metallic
phase is detectable in this study. Above a 20% reduction there are two
phases, the lower oxide and the metal phases. There are solid solutions
of stable concentration here. According to the phase diagram of the Mn.-Fe
sys-te&'., (Ref. 6)9 the solid y-solution is stable at 19'0000. X-ray pic-
tures show a predominant quantity of the solid a-solutiong which is
formed by cooling the y-solution. Admixtures of potassium- or sodium
carbonateB accelerate the reduction of manganoferrits (Fig. 2). A phase
with a Spinell-like lattice, similar to that of the ferrite used, is
present in an 18.93% reduced sampleg but it cannot be proved at 28.9%
reduction. A phase with an NaCl-like lattice (which corresponds to the
sub-oxide phase of MnO), is present in all samples. Its lattice para-
meter increases with the percentage of the reduction and approaches the
size of the MnO-latticep without, however, reaching it (Fig. 3). On the
basis of these data the authors give a reduction mechanism of manganese-
ferrite: when the oxygen io removedg a surplus of metal ions is formed
on the surface of the crystal lattice. They can either form a ferrite

lattice.or a metal phase. Which process predominates depends on the
ratio of oxygen removal rate to the reaction diffusion. When hydrogen
is used for the reduction, the oxygen removal rate is higher than that
of the diffusion. When graphite is used for the reduction both rates
are commensurable. The admixtures of alkali metal salts accelerate the
chemical interaction of both the reducing compound and of that which
is to be reduced. This is related to the variation in the electron con-
dition of the lattice, into which univalent ions penetiate (Ref. 9).

TITLE: Study of equilibrium conditions in the reduction of manganese
ferrite by hydrogen
PERIODICAL: Zhurnal fizicheskoy khimii, v. 36, no. 11, 1962, 9436 2441
TEXT: To find out the structure of ferrites and suitable conditions for
their production, the reduction of manganese ferrite in hydrogen was
studied at 9000C. Manganese ferrites of different compositions were
produced by sintering Fe2 03 - MnO mixtures at '12000C in various atmospheres
(CO ^r, CO + 0 or air), and by sintering Fe 0 MnO - Mn 0 mixtures.

Debye patterns showed that the resulting ferrites were single-phase. The
.reduction was performed in a mixture of water vapor (P.20 . 4.579 mm Hg) and
hydrogen (P. 10-3 - 102 mm. Hg).. After equilibrium had been established

between ferrite and gas mixture, the water was frozen out, the p H measured,
the degree of reduction determined from the H2 consumption, and p 02 the
equilibrium pressure calculated. The phases formed in the reduced ferrite
were identified by Debye patterns. Resultsi Except for those in air, which
were higher due to oxidation, the ferrites sintered in different atmos-
pheres showed approximately the same p H O/PH -values with the same degree
2 2
of reduction. Ferrites containing excess manganese owing to admixture of
Mn3049 showed higher p 02 due to formation of Mn 304 -MnFe204 solid solu-
tions. During the ferrite reduction, the lattice constant of the spinel
phase gradually fell until it was roughly the same as for magnetite. At
10~4 reduction, a lower oxide phase appeared with an NaCI lattice, the
constant of which increased as the-reduction proceeded. At 45% reduction,
a metallic phase appeared, with the lattice constant of iron (2.a61 R).
The reduction of manganese ferrite thus proceeds in two stagest (1) Re-
duction to the lower oxide phase (Fe, Un)G via formation of non-ideal solid

TABSTRACT:.. Equilibrium conditions at 700 to' 900C for the initial
06tages of hydrog4in reduction of manganese-zinc ferrites of varying
:!composition are investigated. The equilibridm' constants wend
idetermined experimentally and the equilibrium partial pressures of
oxygen following dissociation of the ferrites were calculated. The
1:1attice constants were measured. It was shown that both the equilib
i-rium partial pressure of oxygen and the lattice constants of manganese-
