摘要：
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 regions of this system are calculated. Standard thermodynamic functions of formation and standard entropies are estimated for ternary phases AgSnSe2, Ag0.84Sn1.16Se2, and two modifications of Ag8SnSe6 and also thermodynamic functions of Ag8SnSe6 polymorphous transition.
