Qısa məlumat

The paper analyzes the works on optimization of thermodynamic equations of heterogeneous equilibrium using a multi-objective genetic algorithm (MGA) for calculation and multi-3D modeling of liquidus surfaces, boundaries of stable and metastable states of solid solutions of chalcogenide systems YbTe-SnTe, SnTe-Sb2Te3, Bi2Te3-Sb2Te3-PbTe, SnSb2Te4, SnSb4Sb7, Tl9SmTe6-Tl9BiTe6and Tl9SmTe6-Tl8PbTe3-Tl9BiTe6, BiI3-Bi2S3-Bi2Te3of interest for semiconductor technology, U-Nb alloys of interest as nuclear fuel for fast breeder reactors, H2O-MMA (methyl methacrylate) and H2O-furfural systems exhibiting heteroazeotropic behavior. Temperature-concentration dependences of the Gibbs energy of formation of solid solutions from binary compounds, as well as from ternary compounds, are determined using a subregular model of solutions of non-molecular compounds as applied to telluride systems. The uncertainty ranges of temperature and pressure for direct reduction of magnetite to free iron and oxidation of V+3to V+3in titanomagnetite concentrate granules by a mixture of natural gas and hydrogen are determined. The conditions for the precipitation process of aluminum hydroxide from aluminate solutions based on fuzzy logic theory are revealed.
