摘要
采用熔盐电解法，在CaCl2-NaCl混合熔盐中电解还原钛铁矿，制备出了多孔、粒径在10μm左右的Ti-Fe合金，探讨了CaO加入量对电解还原钛铁矿的影响。结果表明，熔盐中添加摩尔分数0～1．O％的CaO促进钛铁矿还原并生成，加快了电解过程；当CaO浓度增加到1．5％后，抑制了CaTiO3的还原。
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.
