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 ...

The system Ag-Sn-Se in the region of Ag2Se-SnSe-Se composition is studied by measuring EMF of cells with Ag4RbI5 solid electrolyte in the temperature interval of 300–450 K. Based on the results of EMF measurements, the temperature of Ag8SnSe6 polymorphous transition (355 K) is determined and the partial molar functions of silver in certain phase re...

AbstractThe results of a thermodynamic study of the Tl2Te–Tl2Te3–TlGdTe2 system by the electromotive force (EMF) method in the temperature range 300–450 K were presented. The partial thermodynamic functions of GdTe and Gd in alloys were first determined from the experimental EMF data for concentration cells relative to the GdTe electrode. The stand...

Polythermal sections in the vicinity of the quaternary compounds Ag2FeSnS4 and Ag2FeSn3S8 have been modeled. The mechanism of formation of these quaternary compounds and their thermal stability have been investigated. Measurements of electromotive force allowed calculations of the standard thermodynamic functions ΔG°, ΔH°, and S° of the Ag2FeSnS4 a...

The Cu2GeS3–Ag2GeS3 system was studied by the EMF method with a Cu4RbCl3I2 solid electrolyte in the temperature range 300–380 K. The formation of wide regions of solid solutions from the starting compounds in this system was confirmed. The partial thermodynamic functions (ΔG, ΔH, ΔS) of copper in alloys were calculated from the equations of the tem...
