Preparation of Ti-Fe Alloy from Titanium Concentrate by Electro-Deoxidization in CaCl₂

Abstract:

Ti-Fe alloy is prepared by the electrolytic reduction of titanium concentrate in molten CaCl₂ under argon atmosphere. The formation mechanism of Ti-Fe alloy is discussed. The impact of electrolytic time on product is studied when electrolytic voltage is 3.1V and electrolytic temperature is 900°C. Results show that Ti-Fe alloy with uniform composition can be obtained by this method. The deoxidize product is iron and TiFe alloy by order. The reduction of Ti is a multi-step process and the intermediate products include CaTiO₃,TiO₂, Ti₂O₃, TiO,Fe, TiFe_2.
