The Ag-Ga-Se system is investigated in the Ag2Se-Ga2Se3-Se region hy DTA, X-ray powder diffraction, microhardness measurements. The isothermal section at 300 K, vertical sections AgGaSe2-Se and Ag9GaSe6-Se, and a projection of the liquidus surface are constructed. The existence of a wide phase separation region is demonstrated, and the types and coordinates and nonvariant and monovariant equilibria are established.
