Qısa məlumat

The results from studying the SnTe–AgSbTe2 system by means of EMF with the solid electrolyte Ag4RbI5 in the temperature range of 300–430 K are presented. The formation of a wide (≥80 mol % of AgSbTe2) region of solid solutions based on SnTe is confirmed. Partial thermodynamic functions ΔG̅, ΔH̅, and ΔS̅ of silver in alloys are calculated from the equations for the EMF temperature dependences. Based on the literature data regarding solid-phase equilibria in the Ag2Te–SnTe–Sb2Te3–Te system, potential-determining reactions are identified that allow us to calculate the standard thermodynamic formation functions and standard entropies of solid solutions (2SnTe)x(AgSbTe2)1−x (х = 0.2, 0.4, 0.6, 0.8, and 0.9).
