INTERACTION IN THE SYSTEM CuGaS2–PbGa2S4

The interaction in the system CuGaS2–PbGa2S4 which is the internal section of quasi ternary system Cu2S–Ga2S3–PbS has been studied for the first time using the methods of differential-thermal, X-ray phase and microstructural analyses and measurement of microhardness and T–x state diagram has been plotted. It was established that the section CuGaS2–PbGa2S4 belongs to a simple eutectic type with coordinates of eutectic point: 60 mol% PbGa2S4 and Т=1015 К. The formation of narrow regions of solid solutions was established on the basis of components
