The quasiternary system Ag₂Se–CdSe–In₂Se₃ was investigated by differential thermal analysis, XRD, microstructure analysis and microhardness measurements. From the results of the investigation and literature data, six vertical sections, the isothermal section at 820 K and the liquidus surface projection were constructed. The nature and the temperatures of the invariant processes in the Ag₂Se–CdSe–In₂Se₃ system were determined. The existence of a quaternary compound, Ag_0.4Cd_0.4In_6.3Se₁₀, was established; the compound melts incongruently at 1055 K.
