The performance of the cathode always has a close relationship with the electro-deoxidation process and its current efficiency. In this paper, the effect of sintering temperature on the electrical resistivity of an ilmenite concentrate cathode was measured. The results showed that the sintering temperature had a significant effect on the electrical conductivity of the cathode. The electrical resistivity of ilmenite concentrate cathode decreased with increasing of the sintering temperature and increasing of the contact area. Besides, the influence of the cathode porosity on electrochemical process during preparation of Ti-Fe alloy in molten salt was studied. The results also revealed that the porosity of ilmenite concentrate cathode had a direct effect on the reduction process. The increasing of porosity was beneficial to the formation of intermediate product (CaTiO3) and improvement of the current efficiency.
