Abstract
The electrolytic reduction process of mixed ilmenite (FeTiO3) and titanium dioxide (TiO2) to Fe-Ti intermetallic alloy in molten calcium chloride (CaCl2) electrolyte was studied. FeTiO3 and TiO2 powders were taken, which was then mixed, milled and pressed into 2.2 g of pellet and heat treated at 1000 °C for 2 h. The pellet was reduced electrochemically in a molten CaCl2 electrolyte at 950 °C and at a constant voltage of 3.0 V. The electrolyzed samples formed by the electrolytic reduction of the mixed FeTiO3 and TiO2 pellets were analyzed using X-ray diffraction, scanning electron microscopy/energy-dispersive X-ray spectroscopy, electron-probe microanalysis. From this analysis, it was confirmed that the mixed FeTiO3 and TiO2 pellets were successfully reduced to a dense Fe-Ti intermetallic alloy consisting of β-Ti (FeTi4) and FeTi phases.
