Physicochemical interaction in the TlSe-Tl2SnSe3-Se quasi-ternary system

The physicochemical interaction in the TlSe-Tl 2 SnSe 3 -Se quasi-ternary system was studied by differential thermal analysis, X-ray powder diffraction, and mathematical modeling. A projection of the liquidus surface and the three-dimensional phase diagram of the TlSe-Tl 2 SnSe 3 -Se quasi-ternary system were constructed. It was determined that this system is of the eutectic type and limited solid solutions based on the initial components form in it. New intermediate compounds were not observed in the quasi-ternary system.
