Direct deoxidization of Ti-bearing compounds was done by using solid oxygen-ion membrane (SOM) molten salt electrolysis and selective extraction of titanium alloys simultaneously. X-ray diffraction (XRD), scanning electron microscope (SEM) and energy dispersive X-ray (EDX) analyses show that the Ti5Si3 alloy can be extracted directly from Ti-bearing blast furnace slag. Metallic impurities such as calcium, magnesium and aluminum were completely removed from products during electrolysis. In addition, TiFex alloys can also be obtained directly from deoxidized ilmenite (FeTiO3) in molten salt. Finally, the electro-deoxidation processes are discussed.〖HJ〗
