*History:*

The Laboratory of Chemical Thermodynamics was organized in 1930 by Prof. Adam V. Rakovskii (1879-1941). From 1943 to 1976 Prof. Yakov I. Gerassimov was the head of the Laboratory. Five doctors of science, 48 PhD's, more than 200 MSc's have been raised in the Laboratory.

*Staff:*

30 workers including 17 scientific workers and 3 associated professors. Doctors of science - 2, PhD's - 12, female - 16, male - 14.

**The head:** Prof. Gennady F. Voronin

*Main directions of researches:*

- experimental determination of the thermodynamic properties of substances with the EMF, calorimetry and heterogeneous equilibria measurements,
- calculation of the phase and chemical equilibria, computing phase diagrams of the stable and metastable states of the multicomponent mixtures,
- calculation of the chemical equilibria in gases, solid and liquid solutions,
- thermodynamic simulation of the technological processes in the field of synthesis and use of new materials: the determination of external conditions required for the existence of the substances, stability and reactions with the ambient gases and surrounding,
- creation of local data bases of self-consistent thermodynamic properties for materials science applications in the areas of high-temperature superconductors, ceramics, alloys, semiconductors and composites,
- development of mathematical methods and software for thermodynamic calculations.

** Main recent results**
are connected with studying high-temperature superconductors. The set of
self-consistent thermodynamic functions of solid phases in the system
Y-Ba-Cu-O has been obtained, thermodynamic models of solid solutions
have been suggested, phase diagrams, stable and metastable equilibria
with superconductors phases "123", "247", "124" have been computed.
Thermodynamic properties other would-be-superconductors in this system
have been estimated.
