Investigation of the thermodynamics of liquid In-Sn-Te, In-Pb-Te and In-Sb-Te alloys

Excess enthalpies of liquid alloys were determined in a heat-now calorimete r at 1073K of the sections In0.5Sb0.5-Te and In0.5Pb0.5-Te, and at 1173K fo r In0.5Sn0.5-Te, In0.5Sb0.5-Te and InyPb1-y-Te with y = 0.2, 0.5 and 0.8. T he association model was applied for the analytical description of the ther modynamic properties of liquid binary tellurium alloys. Additional ternary interaction parameters had to be used for the calculation of ternary excess enthalpies. They were obtained by fitting the calculated curves to the exp erimental data with the least squares method.
