Qısa məlumat

Using the Multipurpose Genetic Algorithm (MGA), analytical models of phase diagrams of the Tl9SmTe6–Tl8Pb2Te6, Tl9SmTe6–Tl9BiTe6 and Tl8Pb2Te6–Tl9BiTe6 systems were obtained as temperature dependence on the composition. The boundaries of the uncertainty band for the liquidus surface of crystallization of solid solutions and the TlSmTe2 compound, as well as the solidus of solid solutions, are determined. According to the model of regular solutions of non-molecular compounds, the thermodynamic functions of mixing solid solutions depending on the composition and temperature are determined. It was found that solid solutions of based on the compounds Tl9SmTe6, Tl8Pb2Te6 and Tl9BiTe6 have thermodynamic stability in the entire concentration range. The analytical multi-3D model of the phase diagram of the Tl9SmTe6-Tl8Pb2Te6-Tl9BiTe6 system was determined and visualized for both the quasi-ternary and nonquasi-ternary high-temperature part of the TlSmTe2 crystallization.
