The starting ternary compounds CuInS 2 and CuSbS 2 and alloys of the CuSbS 2 –CuInS 2 system with the molar fractions of CuInS 2 ( x ) equal to 0.05, 0.15, 0.25, 0.375, 0.50, 0.625, 0.75, 0.85, and 0.95 were prepared and the phase relations in this system were investigated by X‐ray powder diffraction, optical microscopy, scanning electron microscopy, and differential thermal analysis. It was shown that the T–x phase diagram of the CuInS 2 –CuSbS 2 system has a eutectic character with the eutectic temperature of 807 K. The alloys of the CuSbS 2 –CuInS 2 system with the molar fraction of CuInS 2 in the range from 0.038 to 0.941 at room temperature are two‐phased, and the limits of solubility are 0.059 molar fractions for CuSbS 2 in CuInS 2 and 0.038 molar fractions for CuInS 2 in CuSbS 2 .
