Abstract
The Ag–Ge–Se system was studied in the range of compositions Ag2Se–GeSe2–Se by measuring the EMF of the concentration (relative to the silver electrode) circuits with a solid electrolyte Ag4RbI5 in the temperature range 290–430 K. The polymorphic transition temperature of Ag8GeSe6 (320 K) was determined and the partial molar functions of silver were calculated for both crystal modifications of this compound based on the EMF measurements. The thermodynamic functions of formation and entropy of both modifications of Ag8GeSe6 and the thermodynamic functions of its polymorphic transition were calculated.
