INTERACTION IN THE SYSTEM CuGaS2–PbGa2S4

Abstract

The interaction in the system CuGaS 2-PbGa 2 S 4 which is the internal section of quasi ternary system Cu 2 S-Ga 2 S 3-PbS has been studied for the first time using the methods of differential-thermal, X-ray phase and microstructural analyses and measurement of micro hardness and T-x state diagram has been plotted. It was established that the section CuGaS 2-PbGa 2 S 4 belongs to a simple eutectic type with coordinates of eutectic point: 60 mol% PbGa 2 S 4 and Т=1015 К. The formation of narrow regions of solid solutions was established on the basis of components.
