Abstract

The article deals with the phase equilibrium in titanium-containing slag from metallurgical processing of ilmenite concentrates of Shokash deposit on the basis of five-component system TiO₂-Al₂O₃-SiO₂-MgO-CaO have been studied by thermodynamic analysis (TDA). The phase equilibria in two four-component systems CaO-MgO-Al₂O₃-SiO₂ and TiO₂-MgO-Al₂O₃-SiO₂, which are part of the five-component system TiO₂-Al₂O₃-SiO₂-MgO-CaO were clarified and corrected. Thus, the data on the phase compositions of congruently (stably) melting compounds of titanium slag and slag of aluminum- and aluminosilicothermic ferrotitanium as well as slag melts from melting of titanomagnetite ores, etc. have been obtained.

Keywords
