Thermodynamic analysis of obtaining ferroalloy from silicon-aluminum-containing silica clay
The article presents results of thermodynamic modeling of Fe-Si-Al complex containing alloy of the silica clay (77.8 % Al2O3, 11.6 % Al2O3). The modeling is based on the principle of minimum Gibbs energy and fulfilled by means of software complex HSC-5.1. It was found that the joint reduction of silicon and aluminum from an amorphous SiO2 and Al2O3 is characterized by higher thermodynamic probability than from a mixture of a crystalline SiO2 and Al2O3.
