Since Fray-Farthing-Chen (FFC) Cambridge process was proposed in 2000 for electrochemical extraction of titanium from titanium oxide, a great quantity of researches has been carried out to investigate the mechanism of the electro-reduction of the process. Results shows that the intermediate products of perovskite phases are inevitable during the electro-deoxidation process. In this paper, a new perspective focus on the anode behavior was applied. TiO2 and synthetic perovskites mixed in different ratio(CaO:TiO2=1:1/1:2/2:1) are used as the Experimental raw materials., and the behavior of the graphite anode has been investigated. Although the main anodic process in the electrolysis is the oxygen evolution by means of the CO2, a thin film due to the formation of CaCO3 was floating on the molten salt at higher concentration of CaO.
