Abstract: Phase equilibria in the Cu2Se–GeSe2–SnSe2 quasi-ternary system were studied by differential thermal analysis (DTA) and X-ray powder diffraction analysis. A series of polythermal sections, the 750-K isothermal section of the phase diagram, and the liquid surface projection were plotted. Primary crystallization and homogeneity areas of phases were determined, as well as the characters and types of invariant and monovariant equilibria. Extensive Cu2GeSe3-base and Cu2SnSе3-base solid solutions were found to exist in the system along the Cu2GeSe3–Cu2SnSe3 section.
