Title Reaction of lead titanate with;ralts in f~xsions
Periodical Zhur. ob. khim. 24/2, 211-215, Feb. 1954
Abstract The results obtained during the Eitudy of the reaction.between PbT'03 and salts
of vario-as monovalent metals in fusions are presented. The.study was conduct-~'
ed at temperatures up to 1-1000 by mans of a visual-polythermal fusibility
method. The effect of increased*temnerature on the volatility and decomposi-
tion of PbTiO is exnlnined. It was established that PbT103 in fusions with
sodium and no?assium'fluorides, silicates, carbonates, molybdates'and tnng,-
states forms certain eutectic systems which can be used for the formation of
PbT'03 monocrystals in melted media. A great analogy between the chemical
properties of PbTi03 and BiTiOq was established. Seven references: 6-USSR
and 1-Japanese (1950-1953). Tables; graphs.

and fluorides, silicates) carbonates, pyro- and metaphosphates, metaborates,
chlorides,, molybdates, tungstates and other salts of alkal-I and certain dival-.
ent metals in melted state, are tabulated. Of twenty-six systems representing
diagonal sections of ternary systems nineteen were found to be stable sections
suitable for the formation of BaTi%monocrystals in melted media. The chemil-
cal bond, which reflects all proper ies of elements, was used as a basis for
the classification of ternary systems and theory of solubility of salts ih

Periodical : 2hur. Obahchei Ehim. 24, Ed. 593 - 597,.APril 1954
Abstract : Data obtained from the study of eight binary systems and the experimental
material regarding melted salts Indicate numerous cases where sodium
salts show a greater tendency toward complex formation in comparison
with corresponding potassium salts. All tested systems in which potass-
Ium salt wa; present showed no complex formation. These results indicate,
the great difference in the chemical composition of sodium and potassiun
salts. Eleven references; all USSR: 7 since 1951, 4 of 6arlier date.

Periodical Zhur. Ob. Khim., 24, Ed. 6, 936 - 946, June 1954
Abstract Using the visual-polythermal fusibility method, the authors made a thoro-
ugh investigation of the fusibility diagram for the system Ila, Ki~ "104,
P207. A fusion was established between the sodium tungstate'and pyrophos-
phate in a ratio of 1:1 which melted with consequent decomposition at
7670. A fusion existed between the sodium and potassium tungstates in a
ratio of 1:1, which melted with decomnosition at 6890.. The system had
five ternary invariant points, one binary invariant point and one point
of double descent. Three references. Tables, graphs.

Title Stratification in fusions of mutual systems with participation of salts
of first and second groups
Periodical I D.ok. AN SSSR 103/2t 261-263, Jul.11, 1955
Abstract t Experiments conducted with Nal Cal LI and other metal systems showed that
one of the conditions leading to stratification during the fusion of these
elements is the gre%ter difference in:the polarizability of the cations and
enions of the components. The most vivid difference in the polarizability -
was established among ions with 8 or 2 external electron layers and ions with
external electron structure consisting of.18 or 18 plus 2.electrons. The
effect of fluorides on the prevention of stratification in liquid phases is
explained. Nine USSR re.-Verences (1929-1946). Graphs,

ABSTRACT: The Scientific Research Phyaico-Mathematical Institute at the
ROSTOV/DON State University has studied the interaction of
barium titanate, strontium titanate, lead titanate and lead
zirconate with a series of substances in the molten state, A
number of suitable salty solvents for the above mentioned sub-
stances and crystallization conditions have been established.
Several methods for cultivating crystals of barium and stron-
tium titanates and zirconates were applied:
a. Monocrystals of BaTiO and SrTiO were obtained out of
a molten mixture of sodium aad potassium carbonates and poly-

Thus BaTiO crystallization out of molten salts yielded va-
rious modiPications of crystals with anomalous ferroelectric
properties. By varying temperature conditionst it was
possible to grow crystals with different values of the c/a
ratio, including non-ferroelectric crystals.
It was later discovered that these crystals can be carried
through the whole series of states by means of thermal
treatment,
Monocrystals of SrTiO 3 were obtained by two methodst

The monocrystals obtained by these two methods differed in

ABSTRACTz The authors obtained various monocrystals of solid solutions of
the(Ba,Pb)TiO 3 type containing different ratios of components.
Monocrystals of PbTiO were obtained out of a molten mixture of
sodium silicates and Lad metaborate.
All crystals belonged to the perovskite structural type with
tetragonal cells, Spontaneous deformation increased with the
increase of the lead content. The temperature course of the
parameters of PbTiO_ and kBa,Pb)TiO 3 is evidence of the pre-
sence of the phase iransition of the first kind.
The presence of domain structure was established for crystals

After heat treating at a temperature of 13500 for two
hours, the single crystals with variOu6 contents of bari-
um titanate and strontium titanate displayed the follo-
wing ferroelectric properties: the characteristic depen-
dence (with maximum) of the dielectric constant ( ', ) on
the temperature, and the nonlinear dependence of the pola-

with artificially introduced disordering. It was found
in 1951-2 that appropriate thermal treatment could
restore BaTiO3 with poor permittivity curves to the proper
state and the composition to the equilibrium value. In
1915, it was found that foreign atoms could alter the
temperature variation of physical properties and solid

the formation of lamellar crystals is dependent on the cooling condi-
tions and concentration of the melts, but is not dependent on the
presence of Fe203 impurities in the solution. Every set exhibits dif-
ferent values of the dielectric parameters, which can be explained by
different crystal growth conditions. The characteristics shown in
Figs. 1-3 are, however, typical. As may be seen from Fig.1, the depen-
dence of the dielectric constant of BaTiO 3-BaSnO3 on the field strength
of the alternating field iz~ much more marked than is the case with
BaTiO3 crystals. Also the dependence of the reverse dielectric constant
on the magnitude of the constant displacement field is more marked in
them than it is in BaTiO 3 crystals. For the practical use of piezoelec-
tric materials, an important factor is the change of their capacity
with a change of the alternating voltage and simultaneous effect of the
displacing constant field. These dependences are given in Fig.2. The
hysteresis loops exhibit an ordinary form. At the Curie point they pass
over to a straight line. Fig.3 shows the values of the reverse dielec-
tric constant at different points of the hysteresis loops for crystals

5% of Ba Hf 0 sub 3 were quite porous. Measurements made on single crystals
obtained in the form of plates 80 - 500 microns thick from a melt of Ba Ti 0 sub
3, Ba C 0 sub 3, and Hf 0 sub 2 in KF have shown that the Curie temperature
decreces lineally with increasing content of Ba Hf 0 sub 3. The maximum value
of Epsilon is observed for e. composition containing 6 molar percent of Ba Hf 0
sub 3. At roan temperature, tg Delta of single crystals of the investigative
materials ranges from 003 to 0.07. The -ratio of Epsilon at the Curie.point to
Epsilon at room tempera e reaches 20-30. No such increase in Epsilon is
observed in the ceramickspecimens. qmell amounts of Ba Hf 0 sub 3 influence
noticeably the nial properties of the solid solutions. At a frequency of
50 cps, Epsilon increases with increasing field by more than 200 times, and it
may reach 100,000 at a field E equals 0.6 kv/cmj'with the increase of Epsilon
being accompanied by an increase of tg Delta, which goes through a maximum at
approxirmtely 1 kv/cm with increasing E, after which it decreases and reached
0.2. In the region of weak fields, the coefficient of reversible nomeniality of
the single crystals af Ba (Ti Hf) 0 sub 3 is much higher than in .5olid solutions
Ba (Ti 6n) 0 sub 3. The hysteresis loops of these single crystals are
rectangular and reach saturation even at fields off 5 kv/cm. An anomaly is

transparent crystals differed according to the conditions of crystalli-
zation, and exhibited, above all, hexahedral plates and cubes. X-ray
structural analyses showed that they belong to the perovskite type with
a tetragonal cell. Type of structure, symmetry, and parameters were de-
termined by mean3 of powder patterns. The dependence of the parameters
on the concentration is illustrated in Fig.2. These data agree with
those obtained for the corresponding polycrystalline solid solutions
(Ref-5). The refractive index determined by immersion amounts to 2.72
for all crystals examined. The Curie points were found with the help
of a polarization microscope. It was found that monocrystals of lead
metaniobate may be obtained from its solutions in PbO-B 203 melts. Fig.3
shows the surface of the primary crystallization of the system
PbO-B203-Nb2059 which was studied up to 11000C. When the melts finally

that were subjected to a heat treatment at 1300 C has shown that within
a wide concentration range (from PbNb 206 to 90% PbTiO3 and above) there
is a continuous series of solid solutions which do not belong to the
perovskite type. Heat treatment changes the structure of the crystals.
It is assumed that there is a transition from rhombohedral PbNb 206 to
the modification described in Refs. 8 and 99 namely, rhombic Pbffb 206*
The measurement of.crystals that did not undergo a heat treatment
showed a monotonic change of the parameters of rhombohedral PbNb 206
with an increase of concentration of PbTiO 3* The authors thank

TEXT: Melts of the PbO-B203 system were used as solvents for
preparation of the crystals. Molar quantities of PbO and B203
were taken, and mixtures of PbO, TiO2 and Zr02 of given
concentrations added. Single crystals of solid solutions of.
PbTiOg and PbZr03 were grown in this way containing 1.4, 1.7

by X-ray spectrographic analysis. The crystals were gold-yellow
in colour and were 6-sided platelets, cubes or intermediate forms.
The size was up to 4 mm. The colour darkened with increase of
PbZr03- A 24% mixture of 50% PbO and 50% Kb205 was added to the
PbO;B203 melt, heated to 1100*C, held for 7 hours and cooled to
500 C at 20OC/hour. The furnace was then switched off.

Crystals of PbNb206 were obtained which were light yellow in
colour. They were transparent 6-sided-or right-angled platelets.
Various forms were obtained and a photograph shows some of these
forms, Single crystals of solid solutions of PbT'03 and
PbNb206 containing 25,*50, 75 and 90% PbT103 were prepared by
heating PbTi03 and PbNb206 in PbO and B20~ to 10000C, holding
for 3 to 7 hours and cooling to 6000C at 20 C/hour. - The crystals
had a transparent orange-colour and were 3-sided plates 0f--3 mm.
The solidification surface for the PbTiO3-PbNb2O5-(50%PbO + 50%B209
system is given in Fig.2. Measurements of the dielectric
constant and the loss factor were made on the solid solutions.
Fig.4 ghows the relation between e and tg 6 and temperature

The conductivity sharply increases with temperature, the crystal
behaving as a semiconductor. The following conclusions are
arrIved at. 1. In using melts of the B203-PbO system as
solvents, single crystals of the solid solutions Pb(T103 -Zr03)
containing up to 1.39% PbZr03 were obtained for the first time-.
2. Single crystals of PbNb206 were obtained with side lengths

90% PbTiO were obtained. The dielectric properties were
studied o? single crystals of Pb(Ti-Zr)O and it was established
that slight additions of PbZrO do not Lve any influence on the
dielectric propert4fs, as can L seen from Fig.4, and the crystals

TEXT.- The authors describe the preparation of thin monocrystalline
plates of BaTiO 3 - BaSnO 3 solid solutions and of PbTi03 by cooling
suitable welts. Perroelectric properties (nonlinearity, rapid rise of
permittivity at the Curie point, strong temperature dependence of per-
mittivity) were much more marked in monocrystals than in ceramic
BaTiO 3 - BaSnO3 solid solutions. Two other series of experiments were
carried out using charges consisting, apart from K-F of BaTiO3 + Sn

Ths best thermal cycle for preparing plate-shaped monocrystals was.
heating for 5 hours until 9600C was reached; keeping at 950 0C for 20
hours; cooling to 6000 C at 15 - 20 deg/hour. Monocrystals were separated
out by washing in nitric acid. They were six-sided or square plates
(3 - 4 mm sides and 100~k thickness) and many of them were of the mone-
domain t-

index of 2.71 . Their crystal structure vas tetragonal per3vskits. The
room temperatjire permittivity (,C_ - 80) of plates was lower than that of
PbTi03 ceramics or cubic monocrystals; this was probably due to prs-
dominance of c-domains since permittivity is low along the c-axis. At
room temperature the tg cS of plates vas 0.055 (compared -with tg cS
= 0.300 for cubic monocrystals) and the losses rose more slowly, with

PERIODICAL: Zhurnal neorganicheskoy khimii, v. 6, no. 4, 1961, 944-947
TEXT: The melting processes in the system PbO -Nb 20 5-B203 were studied
up to about 20 mole~a of Nb 20 5(Fig. 2); besides, the authors investigated
the out (50% PbO +50% B2 03 ) -PbNb2 06 - PbTiO3in the corner
(50% PbO+ 50% B 20 3) (Fig- 3). The phases of this system cafi be important
because of their piezoelectric properties. The initial substances were:
PbO for analysis, chemically pure B 2031 TiO2for analysis, Nb 20 5 with a
degree of impui-ity of about 2 %, including 1.1 % of Ta 205' X-ray analysis
was conducted by Ye. G. Fesenko, and tests for piezoelectric properties

were carried out by A. L. Khodakov. From the system PbO -Nb 20 5-B20 3P 13
cuts were studied. In the region of high content of B20 3) the system
separates into component parts. The melts solidify in the form of glass.
The major part of the system is occupied by the crystallization surface of
lead metaniobate. Two more phases of the side system PbO -Nb 205 (A and B)
do not remain stable in the ternary system, but decompose already at low
temperatures (Ri 5880C, R2 7300C). During solidification of the melt,
PbNb 0 6 single crystals form in glass which may be removed by nitric acid.
In tKis way, single crystals with an edge of 0.5 cm were obtained. These
crystals adopt piezoelectric pro erties when heated at 13000C for 3.5 hr.
Studies of the cut (50% PbO + 50WB20-j) - PbNb206 - PbTi03 disclosed an un-
interrupted series of mixed crystals between PbTiO 3 and PbNb206' These
rhombic, imperfect crystals of the perovskite type are not piezoelectric.
Only after heating at 13000C for 6 to 9 hr the mixed crystals 75% PbNb 206+
25% PbTiO 3 and 50% PbNb 206+ 50% PbTiO became piezoelectric. There are
