Deoxidization mechanism of preparation FeTi alloy using ilmenite concentrate

摘要

An investigation into the deoxidization mechanism of the electrochemical reduction of ilmenite concentrate to FeTi alloy in molten calcium chloride has been performed. The results show that deoxidization proceeds through a number of individual stages some of which involve reduction of iron, formation and desposition of calcium titanates(CaTiO3), reduction of the various low value titanium oxides and formation of Fe2Ti and FeTi. CaTiO3 is formed because Ca2+ contained in electrolyte take part in the deoxidization process.
