CaGa2Se4–GaSe system

Abstract

The phase relations in the CaGa₂S₄–GaSe system have been studied using differential thermal analysis, X-ray diffraction, microstructural analysis, microhardness tests, and density measurements, and its T–x phase diagram has been mapped out. The CaGa₂S₄–GaSe system has been shown to be a pseudobinary join of the ternary system Ca–Ga–Se. The CaGa₂S₄–GaSe system has been found to contain limited solid solutions based on the constituent selenides. The electrical conductivity of CaGa₂S₄ has been measured and its current–light behavior and photoelectric properties have been studied.
