Cu x Ag 1–x GaS 2 large‐scale blocks were obtained by two‐temperature synthesis method with the following crystallization of the melt. It was established, that crystal lattice parameters are changed according with Vegard's law, and microhardness have an extremum on the base DTA measurements state diagram of AgGaS 2 CuGaS 2 system was built up. The composition dependence of band gap has nonlinear behaviour.
