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 micro hardness 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
