Abstract. Phase equilibria in Cd-Hg-Te system are analyzed in the framework of the
polyassociative solution model. Checking the mentioned model applicability
to description of phase equilibria and search of system thermodynamical
functions were realized by sequential processing the data upon phase equilibria
in initial binary system using computer software. After Hg-Te system,
as the next material we chose Cd-Te system. It was shown that CdTe, Cd2Te3,
CdTe2 and Te2 are predominant complexes of the liquid phase in the considered system.
Determined are parameters of complex creation in a liquid phase. A satisfying
accordance between estimation and experimental data on P-T-X equilibria
in the initial binary system Cd-Te was attained using this approach.
