Abstract
For the first time, by differential thermal, X-ray powder diffraction, and microstructural analyses, phase equilibria in the ternary system Tl9SbSe6–TlSbSe2–Tl4SnSe4 were investigated and the state diagram of the polythermal section Tl4SnSe4–Tl3SbSe3, the projection of the liquidus surface on the concentration triangle, and the isothermal section at 423 K were constructed. The types and coordinates of invariant processes, the lines of monovariant equilibria, and their temperature ranges were found. The formation mechanism and nature of solid solutions based on ternary compounds Tl9SbSe6 and TlSbSe2 were studied in terms of crystal chemistry.
