Тріангуляція квазіпотрійної системи Tl2Se–GeSe–SnSe2

Abstract

Triangulation of the Tl2Se–GeSe2–SnSe2 quasiternary system have been studied. The bications Tl4Ge(Sn)Se4, Tl2Ge(Sn)Se3 and Tl2Ge2(Sn2)Se5 types ternary compounds are formed in this system. At first, Tl4GeSe4–Tl4SnSe4 and Tl2GeSe3 – Tl2SnSe3 sections are divided the ternary system at the three secondary systems: Tl2Se–Tl4GeSe4–Tl4SnSe4 (subsystem I), Tl4GeSe4–Tl4SnSe4–Tl2SnSe3– Tl2GeSe3 (subsystem ІІ) і Tl2GeSe3–Tl2SnSe3–SnSe2– GeSe2 (subsystem ІІІ). Some of the qasibinary sections and reactions into the subsystems ІІІ are discussed.
