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.
