Abstract:
The reaction mechanism of electrochemical extraction of Fe x Ti alloys direct from natural ilmenite in molten CaCl 2 has been investigated. The electrochemical deoxidation experiment process was carried out at 1000 °C and 3.8 V, and a solid oxide oxygen-ion-conducting membrane (SOM) filled with carbon-saturated liquid metal was served as the inert anode of the electrolytic cell. The macro-/micro-structure variations of the samples during electrolysis were investigated. The reaction routes from natural ilmenite to Fe x Ti alloys are proposed and discussed. It is found that element Fe is reduced firstly from ilmenite and thus serves as electronic conductor to accelerate subsequent deoxidation, Fe x Ti alloys can be produced directly from natural ilmenite by electrolysis in molten salt. It is suggested that Fe x Ti phase can be formed directly from Fe x TiO y compounds and/or from deoxidation-generated Ti and Fe through various reaction routes.
