Electromotive force measurement as an important method for determining phase limits in quasi-binary metal chalcogenide systems

Results of studies on phase equilibria in some metal telluride and selenide systems obtained by different authors by thermal analysis were compared. The concentration cell electromotive force method was presented, including the cell construction, measurement technique and possibilities of its use in explaining considerable divergences in phase diagrams published earlier. The method has been shown to be successfully applicable in determination of phase equilibria in the quasi-binary metal chalcogenide systems.
