Essay

The phase equilibrium is specified in the system Tl2S-TiS2. The physicochemical interactions type in the systems of Tl4TiS4 - Tl4SnS4 (I), Tl4TiS4 - Tl4GeS4 (II) were investigated and it is specified - in the system Tl4GeS4- Tl4SnS4 (III). The formation of unlimited solid solutions in the system (I) and limited solid solutions in (II) were established. Unlike literary information, the break of solubility was set in the system (III). The optimum technological terms of synthesis and growing of Tl4TiS4 single-crystals was developed with stable and reproduced properties. The detailed researches and comparisons of thermo-electric properties of Tl4TiS4 poli-, single-crystal and solid solutions were conducted
