ABSTRACT: Glasses having different compositions In the spodumene range were subjected
to thermal treatment over a temperature range of 550-900C for a period of 1-500 hours.
The optical properties, the coefficients of thermal expansion and elongation, and for some
glasses, the volumetric resistance, dielectric loss, glass transition temperature, softening
t temperature and chemical stability were detbrmined by different instruments. The processes
in glasses mineralized with titanium dioxide are explained in detail on the basis of the
experimental data obtained. During the thermal treatment all processes in these glasses

are divided into three periods and two narrow transitionzones separating these periods
from one another. Period I is characterized by the fact that the crystalline phase is
missing, but the glass separates into two phases with the formation and growth of minute
glass droplets of the composition which the crystals formed subsequently in the transition
region will have. Structural changes also occur in titanium oxide and other elements of
var ing valency. In the first transition zone the liquefied glass droplets crystallize.
In
Period 11, the material consists of glass and e3-eucryptite crystals. Their growth and the
structural changes in the titanium compounds continue. In the second transition zone, the
/'~-eucryptite and spodumene crystals are rearranged due to the glassy silica with a
corresponding increase in the total percentage of crystalline phase. In Period M the
material consists of spodumene and a small amount of glass. The complex crystallization
processes are now practically terminated. Orig. art. has: 12 figures and 1 formula.

of the decomposition of the red permolybdate Na 2moo 6*4H20
under isothermal conditions. The decomposition of the red
permolybdate can be classified to the type of reactions
solid 1 = solid 2 + gas. This reaction is governed by the
rules deduced for topochemical reactions. It wasEhown that
a decrease in the water of hydration in the permolybdate leads
to its becoming more stable. Only 2 of the 4 molecules of
water can be removed without liberating active oxygen. The

ABSTRACT: The results of the calorimetric determination of heat effects
are given, which accompany the decomposition of the glassy
substance (obtained from dissociated steam with an electric
discharge). The method of continuous heating on adiab;_~tic
conditions was used. This method makes possible the
determination of heat effects in a relatively quick and
realiable manner. 9 construction of the calorimetric in-
vestigation of the interaction at low temperature of vapour
dissociated in an electric discharge was worked out. Three

-1150C the first exothermic effect begins and that it is
accompanied by a separation of 02' At - 700C the Glassy
substance begins to melt. This goes on till -55 OC. At this
temperature the endothermic, process pasoes over to an
exothermic one. This is accompanied by a turbulent separation.
of 02* It reaches its maximum in a liquid phase at -430C.
This exothermic effect takes place in the melting range of the
eutectic of the R 20-H202 system. In order to take this effect
into account the heat of fusion of the eutectic was determined.
It was 74,5 cal/g. When determining the real value of the
second exothermic effect this quantity was taken into account.
The authors stated that witn the first effect, which began
at -1150C and which was accompanied by a separation of gas
a heat of 78,8 kcal/Mol 02 was separated. The endothermic
effect which is connected with the melting of the substance and

given here prove the process of the ducomposition of glassy
substances suggested earlier by one of the authors
(Nekrasov) (ref. 6). The endothermic effect stated with this
decomposition has not yet been clearly explained. According
to the opinion of the authors this effect had to be
attributed to a change of the state of aegregation with
glassy substances, which would coincide with the explications
in rer. 11.
The authors were advised by Professor 11. 1. Kobozev.

ABSTRACT: The real specific heat of the intermetallic compound CoAl
of stoichiometric composition was investigated by the method of
continuous adiabatic heating. For the production of the alloys
CoAl electrolytically purest cobalt and aluminum (99.99%) were
used. The real specific heat c p was measured for the same
sample in hardened and annealed state in dependence on tempera-
ture. The c p value in the hardened samples rises slowly and
shows a sudden rise at 7400. The sudden rise of the a p value
depends on the order and disorder in the CoAl structure. By
hardening the samples at 12500 a greater disorder is caused
Card 112 than by harlening at 8000C. At temperatures above 8000 all

ABSTRACT: The true specific heat of the alloys PeNiAl and FeCoAl was
investigated according to various methods of treatment of the
alloys. For the prodixotion of the alloys electrolytic cobalt,
nickel, Armco iron, and aluminum with a purity of 99.99 ~t
were used. The melting of the alloys was carried out in the
high-frequency furnace in argon atmosphere. The alloys were
investigated as to their true specific heat and coercive force
H0. The curves of specific heat c p of one and the same
sample were plotted in softened state and after hardening
at 800 and 1,2500 and are shown in figures 1 and 2. The
course of the cp curve of the alloy FeCoAl shows a maximum
at 7000 and of the alloy FeNiAl at 730-7350. The coercive
force of the softened alloys amounts in the case of FeCoAl to
Card 1/3 250 oe and in the case of FeNiAl to 75 oe.

Specific Heat of the Alloys PeNiAl and FeCoAl SOV/78-4-3-23/34
In hardened alloys at 8000 the Hc of PeCoAl - I oe and of
PeNiAl = 63 0e. The c course in hardened samples (8000) is
P
characterized by the occurrence of exothermic effects at
low temperatures. The cP course in samples hardened at
1,2500 proceeds in a similar way. The limit of the exothermic
effect is in the case of the alloy FeNiAl between 300-6000
with a cp minimum at 4600 and in the case of FeCoAl at
400-6400 and a aP minimum at 5600. The nature of the exo-
thermic effect at.,300-6400 could not clearly be determinedy
it is presumably based upon the orientation of the /3 and
A phase with a variation of the structural tension in the
alloy. Alloys hardened at 1,2500 have also an exothermic
effect at 640 and 6800. The considerable temperature effect
increases the coercive force H.. There is no dependence
between high-temperature transformation and magnetic hardening
of the Fe-Ni-Al alloys. It was found that in the system
Card 2/3 Fe-Co-Al the magnetic hardening process proceeds slowly.

Specific Heat of the Alloys FeNiAl and PeCoAl SOV/78-4-3-23/34
At higher temperatures the cp curve proceeds ~,-shaped,
independent of the thermal treatment of the alloys, with a
maximum in FeCoAl at 7000 and in FeNiAl at 730-7350. This
variation in the c curve is connected with the occurrence
of the magnetic trRnsformation in the Curie point. There are
4 figures, 1 table, and 27 references, 19 of which are Soviet.

TITLE: Determination of Dehydration Heat of Some Per-compounds and
Crystal Hydrates of Molybdenum-6
PERIODICAL: Zhurnal neorganicheakoy khimii, 1959, Vol 4, Nr 10,
pp 2242_2243 (USSR)
ABSTRACT: N. I. Kobozev and N. N. Sokolov (Ref 1) investigated the thermal
efficiency of the decomposition of-permolybdates in acid per-
manganate solution and assumed the heat of dehydration to be
equal to zero.~ In order to check this assumption the dehydration
heat was measured in the vacuum.'This experiment is described
in detail. The dehydration heats of Na 2NO04* 2H 20 and
Na2WO 4% 2H20 at 650 were found.to be 5.33 kcal and 5-04 kcal,
respectively. The.heat of dehydrat4 on of Na2MoO 8*4R2 0 had to
be measured at 280, since the permolybdate decomposes at higher
temperature. This compound can give off only 2 moles H 20 with-
out loss of active oxygen. The dihydraLe Na 2MoO8*2H 20 not yet
Card 112 described was obtained. The dehydration heat of the tetra-

hydrate was determined to be 2-4 kcal (on separation of 2 moles
water). The permolybdate Na 2M008*2H 20 differs considerably
from the tetrahydrate. At higher temperature.the active oxygen
is separated under explosion. The fact that the water cannot
be completely removed from the permolybdate without destroying
the molecule permits the conclusion that the compounds in-
vestigated really are perhydrates and not genuine peroxides.
The yellow permolybdate Na oO 6*H 20 can be obtained by hydro-
lysis of the red Na 2MoO8'4H20, but not from Na 2MoO8*2H20.

ABSTRACT: N. I. Kobozev and N. N. Sokolov (Ref 1) dealt with the indirect,
determination of the thermal effect of the decomposition of
permolybdates and have found that direct determination was not
possible. The authors will soon describe the direct determina-
tion made by them. They also repeated Kobozeves and Sokolov's
experiments, the calculation rendered more precise by taking
account of the dehydration heat and other corrections, which
forms the subject of this article. The calorimeter is described

unknown at first. The recalculation of the resultant thermal
effects to pure permolybdate is demonstrated. Experimental
results are listed in table 1. The authors determined the
thermal effect Q 3 of the almost pure permolybdate with re-
calculation to the pure compound and consideration of the dif-
ferent water content and-the thermal effect of decomposition
of the yellow permolybdate (- 37-3 kcal). The value Q 3-77.9 kcal
was obtained for red permolybdate. Figure I shows that the
thermal effect of decomposition of red permolybdates is
proportional to their oxygen content. There are 1 figure,

A3STRACT: In a previous paper (Ref 1), calorimetric investigations were
described whioh dealt with the dooomposition of the solid
condensate (C) obtained by freezing out (at -1960) the steam
dissociated in an electric discharge (as a so-called vitreous
substance). The two-stage decomposition took place with two
exothermic reactions: HO 2+H02 -+ H202 (solid )+02 (1) and
H 0 (liquid) ---) H 0 (liquid) (2). Detailed checking of the
2 4 2 2 +02
,.,as well as
decomposition of (C) (obtained as mentioned above
by a reaction of atomic hydrogen with liquid ozone) indicated
that the resultant data need some correction. Visual observa-

decomposition of (C) the solid phase vanishes at -70 to -0600,
the melting being an endothermic process. Livingstone, Ghorm-
ley, Zeldes (Ref 8), and A. I. Gorbanev, S. D. Kaytmazov,
A. M.Prokhorov, and A. B. Tsentsiper (Ref 9) found that the
concentration of the free HO 2-radicals frozen in the (C) amounts
to 0.3 per cent by weight only. Hence, it results from M
that the portion of hydrogen represents only 41,~; of the total
amount of the formed hydrogen, and the first exothermic effect
is to be ascribed to the thermal effects of reactions and
(2) as well as to the crystallization heat of the amorphous
portion of the condensate. The authors analyzed experimental
data on the first thermal effect (Table); the crystallization
heat of the amorphous M-portion amounted to
-AH - -2.6 kcal/mol H202' which is near the melting point of
H 0
2 2* It is therefore assumed that the devitril4cation of (C)
is directly connected with the presence of H 202~' in.V* condensate.

The value A H= -39 kcal/mol was obtained for the thermal effect
of H2 04-decomposition in the liquid chase of 0 2 and H202' Here-
from the authors calculated the formation heat for H2 04 (from
the components) and the re-formation heat of the HO 2-radicals
into H 204' The respective values are A H- -6kcal/mol and
A.H= -15 kcal/mol H204* They are in good agreement with other
thermochemical data. The structure H-0-0-0-0-H suggested by A. N.
Bakh (Ref 15) is the most suitable for the data obtained. Cal-
culation of the bond energy shows that the energy of the mean
0-0 bond is found within the range 11-43 kcal if the other bonds
are contained in the H 202 molecules according to the corresponding
bonds. There are I table and 17 references, 8 of which are

.TEXT: The heat of formation of manganese ferrite from oxides was calculated
from the difference in the heats of solution between mixtures of manganese
.and iron oxides with a mixture of sulfuric and phosphoric acids at 1400C, on
the one hand, and of ferrite mixed with the same acids, on the other. The
manganese ferrite was produced at 11000C in nitrogen from a potassium
magnesium sulfate of the composition 1/3 NnSO 4' 2/8 FeSO 4. (NH 4)2 304' 6 H2 0 by
thermal decomposition. NnO was produced by a reduction of Mn 304 with hydro-
gen at 7000C, Fe 203 by decomposition of Mohr's Salt at 8000C. The heat of
reaction of the oxide mixtures amounts to AH - -77.7�0-5 kcal/mole, and that
of ferrite amounts to AH -73-7�0-7 kcal/mole. Accordingly, the heat of

formation of XnFe 20 4 from the oxides amounts to AH - -41cdal/mole at 4130K.
From the heats of formation of the oxides at 298.20K, mentioned in the
literature,,& %nO - -92.0kcal/mole and AH Fe 20 3 ' -196 k-.al/mole, one obtains
-292kcal/mole for the heats of formation of KnFe20 4 from the elements.
According to H. Kedeady and A. Tauber (J. Amer. Ceram. Soo., 12, 425, 1956),
the formation of MnFe 20 V according to the equation
2Mn 304 + 6 Fe2o3 - 6 MnFe 204 + 02 starts only above 10000K, preferably

ABSTRACT: The authors investigated the industrial alloys A1jXO-1 and
ANKO-2. For ANKO-1f the authors found the approximate com-
position of 1 W- Nit 10% Alg 12~ Co, 6% Cu (restt Fe)j and for
ANKO-2, 20% Xi, 9% Al, 15dl. Co, 4~ Cu (rest.- Pe). The authors
determined the real specific heat c continuous adiabatic
heating in a calorimeter (Ref 11) . ?h'eyalloys were heated to
12500 in an argon atmosphere and then hardened in ice water,,
Hardening was controlled by measuring the coereivity H by the

ballistic method. The values obtained for c are given in the
figures 1j2, those of H. are listed in a tatle. The findings
were as followss 1) tempering of hardened alloys at low tempera-
tures is accompanied by an exothermic effect. 2) This effect
is probably caused by the magnetic transfo*rmation of the weakly

disappears, since meanwhile a separation of the P- and
phase has occurred- 3) The exothermic effect occur-ring at
610 - 6800 is caused by the magnetic hardening of the alloys,
since it is accompanied by a eharp increnoe in H.. The alloys
ARKO-1 and ANKO-2 are distinguished from the alloy FeNiAl by
their greater magnetic force. 4) The endothermic effect ast 7600
observed in the alloy ANKO-1 is probably due to the trans-
formation at the Curie point. Similar effects were observed in
FeCoAl (7000),and FelTiAl (7350), The transformation point c-f

Ye. I. Shpital'skiy was celebrated on October 12, 1959. Shpitallskiy, Pro-
fessor of Moskovskiy universitet (Moscow University) and Corresponding
Member of the Akademiya nauk SSSR (Academy of Sciences USSR), was a student
of Professor I. A. Kablukov at the fiziko-matematicheskiy fakulltet
Moskovskogo universiteta (Department of Physics and Mathematics of Moscow
University) where he acquired the right of holding academical lectures.
He left Russia for some time to work in the field of catalysis at several
foreign universities. Back to Moscow he was appointed assistant to the
kafedra neorganicheskoy khimii (Chair of Inorganic Chemistry) whore he
hold a practical course on physical chemistry. lie was then a collaborator

of N. N. Petin, later Professor of Moscow University. It was at that timo
that Shpitallskiy began research work on homogeneous catalysis which was
the principal field of his scientific work until his death. During the
First World War he was engaged in the development of explosives and in
the synthesis of phosgene, in cooperation with A. V. Pamfilov, K. G.
Khomyakov, Y*. A. Shilov, V. V. Ra%umovskiy, E. F, Krauze, M. G. Stolitsa,
V. S, Zaykov, Ye. F. Dentgin, and others. At that time Shpitallskiy close-
ly cooperated with N. D. Zelinskiy. In 1923 he resumed his Otudies on
homogeneous catalysis and worked at Moscow University together with his
collaborators A. D. Funk, P. I* Sokolov, V. V. Monblanova, V. A. Komandinv

he published hie principal work on the theory of catalytic intermediates.
This work contains many exact and concise formulations which are still
considered to be of fundamental importance In this field. Shpitallskiy
also specialized in applied and theoretical electrochemistry. There is

TEXT: The authors measured true heat capacities of U308 up to
10000C~ A method depending on the constant heat flow at a given
temperature was used. Accuracy of the determinations was 1 - 2 % up
to 6000C and 2 - 3 % up to 10000C~ U308 was prepared by heating
chemically pure ammonium uranate at rv 8000C. before a sample was
placed in the calorimeter it was neated slowly to 6000C and then
slowly cooled to eliminate strains. It was found that U308 under-
goes two phase changes, one at 7700C and the other at 9400C. Thus
U308 can exist in the form of 3 phasesg aq stable up to 77010, P
(7700 - 9400C) and y (above 9400C). The heat capacities are given
in 1he lable. The heats of the phase changes observed were calcula-
ted from the measured heat capacities by comparing areas (I) enclo-

would exist in the absence of the phase change. The heats were 265

for the P ---),y transformation. becondary heat effects were also ob-
served to take place before the first and the second phase changes
(25 and 65 cal/mole respectively) which were due to transformations
of the supercooled phases. There are 1 figure, 1 table and 7 refe-

PERIODICAL: Zhurnal neorganicheskoy khimii, v. 6, no. 11, 1961, 2433- 2435
TEXT: The authors deal with the problem of energetic characterization of
highly coercive intermetallic compounds on NiAl (FeAl) and CoAl basis.
The specific heat of the compound NiAl was tested on two samples melted
from the electrolytic metals in argon atmosphere- Sample 1 had a
stoichiometric composition (68.6 � O~5% by weight of Ili), the second
contained an excess of Al (67.7 "' 0-5% by weight of Ni) to study the
influence of Al. The samples were heated at different temperatures
(600 - 1300'C) and then quenched in ice water. The curve cp . f(t) was
obtained by means of a calorimeter described by the authors in Zh. obshch,
khimii, 24, 1954. Fig. 1 shows the results for sample 1. Sample 2 shows
no essential differences. An exothermic effect takes place between 550
and 6500C. In consideration of roentgenographic data of I. Isaychev,
