Abstract
We determined the Gibbs free energy, enthalpy, and entropy of formatio n for CdTe-HgTe, ZnTe-CdTe, ZnTe-HgTe, and ZnSb-CdSb solid solutions b y measuring the emf of high-temperature galvanic cells. All the invest igated solid solutions show positive deviations from Raoult's law. The thermodynamic stability of all the solid solutions decreases with dec reasing temperature, and the energetics of formation depends on the in teraction between the components of the metallic sublattice.
