THERMODYNAMIC INVESTIGATION OF THE PbTe–AgSbTe2 SYSTEM BY MEANS OF EMF METHOD
S.H.Mansimova

 2PbTe–AgSbTe2 system was investigated by measuring the electromotive force of the concentration with respect to PbTe chains in the temperature range of 300–450 K. A wide region of PbTe-based solid solutions (20–100 mol% PbTe) was found in the title system. The partial thermodynamic functions of PbTe and lead in the alloys are calculated from the equations of the temperature dependences of the EMF. Standard thermodynamic functions of formation and standard entropies of solid (2PbTe)x(AgSbTe2)1-x (х=0.2, 0.4, 0.6, 0.8) solids are calculated by integrating Gibbs-Duhem equation along the 2PbTe–AgSbTe2 section using literature data on the relevant thermodynamic data for Ag2Te, PbTe and Sb2Te3 compounds
