Abstract

Carbothermal selective reduction of simulative titanium slag and various titanium raw materials were presented and SiO₂ was found to be partially reduced, forming a series of Fe-Si alloys during the process. Thermodynamic analysis of the selective reduction between TiO₂ and SiO₂ was performed using HSC 6.0 software, then a series of equilibrium experiments were designed and presented. The activity of Si reduced from SiO₂ was affected by the presence of Fe reduced from FeOx and the generation of Fe-Si alloys, promoting the reduction of SiO₂ in the whole process. The results of experiment are in great accordance with the calculated data obtained from thermodynamic analysis.
