Abstract
The TlS-CuCr₂Te₄ system was studied and its T-x phase diagram was constructed using complex methods of physical and chemical analysis: differential thermal analysis (DTA), X-ray diffraction analysis (XRD), microstructural analysis (MSA), as well as determination of density and microhardness. It has been established that the phase diagram of the system is partially quasi-binary. Eutectic equilibrium and peritectic transformation occur in the system. In the system at room temperature, solid solutions based on the CuCr₂Te₄ compound reach 10 mol % TlS, and solid solutions based on TlS are practically not established.

Keywords: system, phase, solid solution, quasi-binary, eutectic.
