Qısa məlumat

The results of the study of the PbSe—AgSbSe2 system by measuring the emf of concentration chains with respect to PbSe in a temperature range of 300–450 K are presented. The formation in the system of a wide (37–100 mol.% AgSbSe2) region of solid solutions based on AgSbSe2 is shown. The partial thermodynamic functions of PbSe and lead in the alloys are calculated from the equations of the temperature dependences of the emf. The standard thermodynamic functions of formation and standard entropies of solid solutions (2PbSe)x(AgSbSe2)1−x (x = 0.4, 0.6, 0.8, and 0.9) are calculated by the integration of the Gibbs—Duhem equation over the PbSe—AgSbSe2 section using the literature data on the corresponding thermodynamic data for compounds PbSe and AgSbSe2.
