| Abstract: |
| Porous ferrotitanium alloy with grain size of 10 μm was prepared by molten salt electrolysis of ilmenite in eutectic CaCl2-NaCl melts. The effect of CaO dosage on reduction was discussed. The results show that 0~1.0% (mole fraction) addition of CaO promotes reduction process of ilmenite to form CaTiO3 and electrolytic kinetics. Addition of CaO of 1.5% above restrains reduction of ilmenite. |
