Phase equilibrium in the system Cu2Se–HgSe–GeSe2

The phase equilibria in the quasi-ternary Cu2Se–HgSe–GeSe2 system were investigated using methods of physico-chemical analysis. Four polythermal sections were constructed, namely Cu2HgGeSe4–GeSe2, Cu2Se–Cu2HgGeSe4, Cu2HgGeSe4–Hg2GeSe4 and Cu8GeSe6–Cu2HgGeSe4 as well as the projection of liquidus surface on the concentration triangle.
