Abstract. In the framework of the theory for associated solutions comprising several complexes of various compositions in a liquid phase, analyzed are phase equilibria in Cd-Hg-Te systems. Checking this theory as to the description of phase equilibria in a system as well as a search of model thermodynamic parameters were performed by the way of sequential computer processing the respective experimental results for initial two-component materials. Hg-Te system was chosen as the first model one. It was ascertained that HgTe, HgTe2 and Te are dominating complexes in the liquid phase of this system. Determined were the complex-creative parameters in the liquid phase. As to P-T-X equilibria in Hg-Te system, we reached a satisfying accordance between calculation and experimental data.

Keywords: polyassociative thermodynamical model, phase equilibrium.
