THE THERMODYNAMIC INVESTIGATION OF SOLID SOLUTIONS (2PbSe)x(AgBiSe2)1-x BY E.M.F METHOD WITH SOLID ELECTROLYTE
The system 2PbSe–AgBiSe2 has been studied by e.m.f. method with solid electrolyte Ag4RbJ5. By the analysis of experimental data the formation of wide (to 90% AgBiSe2) area of solid solutions on the PbSe base is established. From the equations of temperature dependences of e.m.f. the partial thermodynamic functions () of silver in alloys were calculated. On the basis of solid-phase equilibria diagram of system Ag2Se–PbSe–Bi2Se3–Se the potentialformation reactions have been established and standard thermodynamic functions of formation and standard entropy of solid solutions have calculated
