Andrei Georgievich Morachevskii
(to 75th Birthday Anniversary)
On October 1, 2001, Andrei Georgievich Mora-
chevskii, a known scientist working in the field of
physical chemistry of metals and alloys and high-tem-
perature electrochemistry, doctor of technical science,
professor, honored scientist and technologist of the
Russian Federation, head of Chair of Physical Chem-
istry at St. Petersburg Technical University, and
deputy Editor-in-Chief of Zhurnal Prikladnoi Khimii
was 75. He also accomplished 50 years of engineer-
ing, scientific, and pedagogical activities.
In 1950, A.G. Morachevskii graduated from Len-
sovet Technological Institute in Leningrad as a specia-
list in physical chemistry. In 195131953, he worked at
enterprises of the Ministry of Interior. At the Kras-
noyarsk plant of nonferrous metals he took direct
part, under supervision of profs. Ya.I. Bashilov and
R.L. Myller, in the development of a technology for
electrolytic manufacture of rhodium.
He became a postgraduate student at Kalinin Poly-
technic Institute in Leningrad (now St. Petersburg
State Technical University) in December 1953; an
assistant at the chair of physical chemistry at the same
institute, in 1956; a docent at the same chair, in 1961;
a professor, in 1970; and headed the chair of physical
chemistry in 1973. He backed his candidate disserta-
tion in 1957 and doctoral dissertation in 1969.
Andrei Georgievich has performed extensive in-
vestigations of thermodynamic and other properties of
binary, ternary, and more complex metal systems in
liquid and solid states. He studied in detail the ther-
modynamic properties of liquid alloys with strong
interatomic interaction and revealed characteristic
features of the concentration dependence of thermo-
dynamic functions in these alloys. Morachevskii and
co-workers were the first to study the thermodynamic
properties of dilute solutions of alkali and alkaline-
earth metals in various liquid3metal solvents and gave
detailed recommendations on how to calculate the
thermodynamic properties of ternary and more com-
plex metal systems from data on binary subsystems.
Morachevskii paid much attention in his works to
computer simulation of thermodynamic properties of
liquid metal systems with varied nature of component
interaction and gave recommendations on compiling
an appropriate database.
Morachevskii and co-workers studied the thermo-
dynamic properties of a great number of chalcoge-
nides and metal3chalcogen systems, developed new
investigation techniques, studied equilibria between
the chalcogenide and salt phases, and analyzed the
interaction of sulfur and sulfides with molten salts.
The thermodynamics and kinetics of alloying on
liquid and solid electrodes and processes of joint dis-
charge of impurities at liquid cathodes were studied in
detail on various objects.
In cooperation with a number of institutions, Mora-
chevskii took part in large-scale investigations in the
field of manufacture of high-purity metals, production
of alkali metals and their alloys, and development of
new chemical power sources for various purposes. In
recent years, the scientist has been paying much atten-
tion to creating an environmentally safe technology
for processing of secondary lead and to new methods
for refining of black lead.
In 1986, Morachevskii was awarded, as a member
of a group of researchers, a State Prize of the Ukraine
in science and technology for the study [Physico-
chemical Foundations, Technology, and Industrial
