Abstract

An optimized set of thermodynamic functions for the Sb-Se system has been obtained by the computer operated least squares method. The liquid Sb-Se alloys have been analyzed in terms of two different models, the two sublattice model for partially ionized liquids after Hillert and the associated solution model. In the latter 'Sb2Se3' species are postulated to exist in addition to monomer Sb and Se atoms. In both models ten parameters, corresponding to quasisubregular interactions between monomers and associate (associate model) or between neutral and ionized atoms (partially ionized liquid model) were used to describe the thermodynamic functions of the liquid. The intermediate compound and the pure elements were treated as stoichiometric phases.
