The In3As2Se6-In3As2S3Se3 system has been investigated by methods of physicochemical analysis (DTA, X-ray powder diffraction, MSA) and by microhardness and density measurements. The phase diagram of the system, which is the quasi-binary section of the As-In-S-Se quaternary system, has been constructed. The region of the In3As2Se6-based solid solutions is extended to 7 mol %, and the In 3As2S3Se3-based region to 15 mol %. A new quaternary compound In6As4S3Se9 is found in the system.
