TITLE: The Effect of Added -Alumina and Corundum on the
Rate of Decomposition of Aluminate Solutions

ABSTRACT: This is a contihuation of studies (Abstract 77626) on
the rate of decomposition of aluminate solutions under
the influence of added aluminum-oxide grains. This time,
the authors used ' -alumina and corundum seedsand the
transitional products between the two, to accelerate
aluminate decomposition by growing crystals. The
three types of seeds were produced on annealing
hydrargillite at 8ooo C for 4 hr, diaspore at 1,2000 C
for 5 hr, and hydrargillite at 1,1000 C for 12 hr,
respectively. Figures 1 and 2 illustrate the seeds of

effectively accelerate the decomposition of dis-
solved sodium aluminate after a certain period of
induction, while corundum does not affect the
aluminate decomposition during any duration. The
induction period decreases with the increasing
quantity of the seeds relative to that of the alu-
minate solution, i.e., with the seeding ratio.
Organic impurities first reduce the decomposing power
of ..'-alumina, but later increase it considerably.
The decomposition of' aluminates by -alumina gives
rise to the precipitation of extremely fine aluminum
hyd'roxide. UP to 30% of the grains remain smaller
than 40 - .' Small amounts of organic impurities
increase this fraction up to even 70%. However, the
higher contents of organic substances make the hydroxide
slightly coarser. Larger quantities of seeds (seeding
ratios 0.2-0-5) also reduce the grain size of the
hydroxide. The precipitate, generated by the
transitional products from --alumina to corundum,

in which the majority of grains vary from
across. X-ray diffraction data proved that all the
precipitates consist of hydrargillite and the surface
layers of the seeds themselves also turn into hydrar-
gillite during the initial period of induction. Perhaps
-alumina first turns into boel-nnite, then into
bayerite found in the X-ray diffraction photographs,
then into hydrargillite. Electron microscopic data
disclosed the composition of '7"-alumina of amorphous
minute particles, whose porous aggregates have large
surfaces per minute volume. During the induction period
they become covered with dendritic crystals of boehmite
and hydrargillite, 0.1-0.5 ' long and 0.11 across,
whose crushing off at stirring of the solution produces
numerous new crystallization centers. Some of the fine
grains of . -alumina recrystallize into hydrargillite
completely and form pseudohexagonal Dlatelets. In
conclusion, the authors state that the seeding capa-
city of boehmite and ".,*-alumina is related to their
instability in the presence of hydrargillite.

TEXT.~, WiUstite decomposition below 570"C is important in both
scaling and iron-oxide reduction. The authors have therefore
carried out an investigation in which special attention was paid to
changes in the microstructure of the free W"Ustite surface during
deco.;rnsition and to the kinetics of the process as a whole. The
process taKes place in two stages:

wustite scale was chipped off to give 4 x 10 x 0.3 mm coarsely
crystalline plate specimens. These plates were -vacuum annealed at
350'C for -rarious periods., Decomposition was studied by
qualitative X-ray structural phase analysis on the powdered scales
in a high-.resolution camera. The lattice parameter of Vomstite and
its decomposition products were determined, Magnetic analysis
(Ref.10.~ Kifer, I.I. and Pantyushin, V.S., Testing of
Ferromagnetic Materials,Gosenergoizdat, M~-L., 1955) was used for
following the process quantitatively, the specific magnetization
being determined with the &id of a standard nickel specimen, An
electron microscope with a resolution of 100 A was used to study
decomposition on the free surface, The inner and outer faces of
the scale were studied by X-ray structural analysis; rapid
photography with focusing on the strongest structural lines of the
phases was used for phase analysis-, the parameter was determined
by back reflection. KaCo radiation was used in all the X-ray work.
Powder X ray patterns showed the initial specimens to be FeO.9250
but there were signs of the start of decomposition on the
outer side of the scale, The lattice parameter there was 4.299

Observations oil the decomposition at 3500C shoured that within
15 111inutes the procelss bad spread to the inner face. At the outer
face there was more metastable than original Iw'ustite. Vi th
ftirther decomposition, llv'ustite disappeared first from the outer
and then the inner face; the hypoeutectoidal formation of
magnet-ite was accompanied by the appearance of fairly dense
formations at both the inner and outer faces. The course of the
process is shoim by Fig.11 (specific saturation magnetization as
as function of' time (lop, scale) in hours): in about I to 1.5 hours
the first-stage reaction M.is completed. This enables a. to
be checked by calculation, values of x and y being obtained

obtained. After 2 hours holding at 3500C, the second
eutectoidal-decotaposition stage of the process begins, iron being
detected on the outer side of the scale and, after 5 hours, on the

size appeared. This porosity is more pronounced ttian that in the
first stage. Pore formation is due to coagulation of vacancies
caused by diffusion of iron ions, which in the U'rustite lattice
occurs more rapidly than tdiffusion of oxygen ions. There are

at temperature 350-375 C with 2 % of diaspor seed. The results of
the experiments confirmed that titanium oxide appreciably lowers
the leaching rate of diaspor and bemite, but has no effect on the
dissolving rate of hydroargalate. It was also confirmed that tita-
nium oxide inhibition at a temperature of 150'C and higher pre-
vents the leaching of bemite and diaspor"but on reaching 230" it
no longer prevents the leaching rate of bemite while the solution
of diaspor is still inhibited. In this respect, Ti02 gel and ru-
thile differ, the latter being less active. In the presence of
waste (3-4 % of the initial weight of solid phase), the inhibiting
action of titanium oxide is much smaller and at temperatures above
1750 becomes practically zero. The oxides of silicon also deter
the leaching of aluminum hydroxide, but to a lesser extent than ti-

tron microscopy has confirmed N.K. Druzhinina's suggestion on the
mechanism of the inhibitive action of titanium oxides, I.e. the
formation of protective films on aluminum hydroxide. The thinness
of film is appreciably less than 100 X and on the addition of
waste films were not formed. With an increase in leaching timet
the protective films crystallize into needle-shaped crystals which
still form protective layersp but now these are porous and alka-
lies diffuse to aluminum hydroxide and the dissolving rate is high-
er. Additions of silicon oxides form crystalline protecting films
of zodium aluminum silicates on aluminum hydroxide insulating it
from alkaline attack. The formation of aluminum silicates on the
surface of aluminum hydroxide crystals can be explained in the
following mariner: Silicon compounds contained in bauxite react
with alkaline aluminum solution to form sodium silicate which. in
turn, reacts with sodium aluminate to form a complex compound qa20-
A120~-2SiO2.2H20. The form of reaction, state the authors, is pro-

TEXT: The decomposition of vustite on its free surface and the quantitative
characteristics of the decomposition kinetics were studied. Wustite
produced by oxidation of Armoo iron in CO-CO 2 atmosphere was chipped off
and temDered in vacuo at 3500C. Phase composition and parameter were
determined by x-ray structural analysis. Polystyrene carbon replicas of
the free surface of the specimens were examined electron microscopically.
The magnetic saturation moment was measured by means of magnetic analysis
in a ballistic apparatus. Wustite had a parameter of 4.295 1 in its
original state. This corresponds to the formula Fe 0.907 0. It bas been
found that decomposition begins an the outer surface of the scale and is
here more intensive, since this surface is richer in 0 2* Primar~, magnetit6

reaction: (1 -4Y)Fe 1-x 0 --* (1 - 4X)Fe 1-Y 0 + (x - Y)Fe3 04; x> y (!). 'he
resulting metastable wustite contains much less oxygen in the surfar,~
layers (Fe 0.9840 ) -than in the center (Fe 0.9630 ). This is indicative of
strong decomposition on thu free surface, where crystallochemical
oonversion is much easier. Eutectoid decomposition is determined based on
the occurrence of --','ron and the constancy of the parameter of metastable
wuaiite,, It proceeds according to the reaction: 4Fe 1-Y 0 ----PFe304
+ (1-4Y)Fea (2), This decomposition is accompanied by a chRracteristic
change of the surface microstructure. Numerous fine pores (of about 0.1 ~L)
are formed. The mechanism of this process is: On leaving the wustite
lattice iron ions leave vacanciez. coagLlate to micropores which
are not overgrown by the magnetitr - ivnating from vustite. Additional
annealing of the specimens (at )UOOC) nf;er decomposition reduced the
porosity and revealed clearly the microstructure. Both the large primary
magnetite c_rystals and the eutectoid could be easily distinguished.
Microcrystals (of about 0.5 g) of the secondary magnetite became visible

insignificant (about 13 ~5 by volume). Probably, Fe forms intermediate
layers between the magnetite microcrystals. The curve as(t) wag plotted
(Fig. 4) as a result of magnetic analysis and shows that the specific
intensity of saturation magnetization of wustite specimens is a func':ion
of the annealing time at 3500C. The experimental values of as could be'
used to determine the decomposition degree in any intermediate stage and
to estimate the decomposition rate in different periods. This became
possible owing to the constancy of the quantitative interrelations
b,etween the phases formed. The rate during the first period (pre-eutectold
separation of magnetite) exceeds that of the second period (eutectoid
de^~omposition) by a factor of about seven. There are 4 figures and

TITLE: Mechanism and kine:ics of the decomposition of
wustite. II

TEXT: In an earlier paper (MM, v.12, no.5, 1961, 697) work on
wustite decomposition at 350% was reported. In this paper
wustite decomposition at 400 and 500*C was studied. In the
present work the same batch of wustite was used in the form of
platc!3 _T scale 0.3 mm thick with a.lattice parameter of ~--302
to Fe3.9250- AnTiealing was carried out in vacuo
(10-4 mm Hg). The saturation magnetization was determined an a
function of annealing time, the same specimen being used for
constructing a complete curve. X-ray patterns were taken from
the same specimen to obtain the phase analysis of the inside and
outside of the scale. A separate specimen, which had undergone
the same treatment as the other specimen, was used for the X-ray

powder method deterwir)ation of lattice parameter. Changes in
the surface'microstructure during decomposition weize followed with
the aid of an electron microscope (resolution 100 A). The work
suggested that in addition to the iron + magnetic eutectoid
the surface contains primary magnetite crystalw. The decomposition
must follow the equation
4Fe 1- X0 -. Fe304+ (1 - 4x)Fe, (x = 0.075)
The process at 5000C is much slower than at 350
OC and is
different in ocher ways. This is explicable on the basis of the
two-stage mechanism. There are 2 figures.

PERIODICAL: Akademiya nauk SSSR. Doklady, v. 142, no. 2, 1962
TEXT: The rate o' tnermal decornosition of wustite at 400 and 500 0C was
investigated. The decomposition products were subjected to X-ray
structurELl and electron-microscopir.; examinations, and the kinetics of the
process was clarified by measuring the variation in specific magnetization
saturation us during heating. Decomposition follows the reaction
4Fel-x 0 ->Fe504 + (I - 4x)Fe; x = 0.093. Details of the process; The
preeutectoid sep~tration of Fe 3()4and eutectoid decomposition are caused
by diffusion of iron ions out of lattiee points; coagulation of vacancies
to pores which are not immediately filled with Fe 304" This porosity
facilitates the tran9formation of neighboring sections. Recrystallization,
however, is also accelaratea with increasing temperature. The pores are

of the dissolution and growth of crystals of alumina in alkaline Al solution's vrith
ayer method. The, laboratory work was primarily done
especial reference to the B
at the Institute; indusIrial experpnents were performed by the Aluminum industry.',
Investigation methods employed:Mlectron microscope, X-ray diffraction, crystal-,
optical and.chemical methods of'i-naly-sis. Ea-iffir stages of the authors' work we:ie~__

on the mos tin~te resting data on the dis,solution and growth of Al-hydroxide
crystals. (1) Procqsves of dissolution (leaching). Hydrargillite crystals in tinsat-1
urate alumina solutions, when heated to nearjb. p., breakup into fragments. Upon:
this initial commint~tion, they dissolve prorr~ptly. Diaspore crystals usually dis-.-
,solve at the faces$ )V#h the formation of fissures and perforations. At times, 'the
r
holes in bernite o. dja~spore exhibit a sharply defined hexagonal shape. When Al
hydroxides with addMons of Si oxides are leached, growths of fairly equiaxial
crystalline formations of Na hydroalurno silicate (sorxie'bf'l.6_-~_rnicron diam) form on
the dissolving particles. Upon full dissolution of the hydroxide crystals or- which
these spherical part~Oe% had formed the latt~'r exhibit apertures. Experiments
show the presence of -films of Ti compounds on the dissolving boirmite and diaspore
crystals. During leaching these films cryst.allize into acicular crystals visible
under an optical microscope. Photographs of these formations are shown in the
article. (Z) Crystallization processes (separation of Al solutions). Without stirring,
alumina solutions foym practically only antiskeletal forms of crystalline growth, so
that crystals of hyd;argillite grow primarily.in the form of lamellar dendrites.
-Lamellar growths form an the plane of the pinacoid. There are virtually no pris-
matic growths. Thoroughly stirred alumina solutions, ex~ecially withprimer, give
rise to a greater probability of the deforma~i6n of growths and, hence, various de-
fects. When, in a lam'jella.r growth, spiral dislocation occurs, it may grow into a

under the action of nonhydrargillitic P*rimers for industrial purposes is
obtained with the use of a bemite primer obtained by 2500C roasting of hydrargyl-
lite. Optimal primer ratio: 0.2-0.3. A brief survey is also given on the process, of.
