Phase equilibria in the system Tl-Se-Cl were studied in the region Tl-TlCl-Se by DTA, X-ray powder diffraction, emf measurements concentration circuits (-) Tl/glycerol + KCl + TlCl/(Tl-Se-Ce) (+), and microhardness measurements. Several vertical sections, an isothermal section at 400 K, and the liquidus-surface projection were constructed. The primary crystallization regions and homogeneity regions of phases were determined, including the α phase of variable composition based on Tl5Se2Cl, the only ternary compound of the system. The types and coordinates of invariant and monovariant equilibria on the T-x-y diagram were determined. From the results of emf measurements, the standard thermodynamic functions of formation and the standard entropy were calculated for the compound Tl5Se 2Cl. © Nauka/Interperiodica 2007.
