Abstract

The paper presents the results of a study of the solid-phase equilibria and thermodynamic properties of the Sn-Se system by electromotive forces (EMF) measurements of concentration cells relative to the tin electrode. From the EMF measurements, the relative partial molar functions of tin in the alloys, the standard Gibbs free energy and the enthalpy of formation, and the standard entropies of the SnSe2 and SnSe compounds were calculated. A comparative analysis of the results obtained with literature data is carried out.
