| 摘 要： | 利用固体透氧膜(SOM)法研究钛铁混合氧化物短流程直接制备钛铁合金。在熔融CaCl2熔盐体系中，以二氧化钛和氧化铁的混合氧化物压片为阴极，氧化钇稳定氧化锆管(YSZ)内的碳饱和铜液为阳极, 在1100 ℃，槽电压3.5 V的条件下电解2~6 h。经SEM、EDS、XRD等分析表明：二氧化钛和氧化铁被电解还原为钛铁合金，直接从氧化物制备钛铁合金是可行且高效的

| Abstract: | The direct synthesis of TiFe intermetallics from the mixed oxide precursors was studied by the solid oxide membrane process (SOM). Fe2O3 and TiO2 were mixed in molar proportions of 1:2 and 1:1, sintered at 1150 oC for 2 h, electrolyzed in molten CaCl2 at 1100 oC using a YSZ anode at a potential of 3.5 V for 2-6 h. The product was examined by SEM, EDS and XRD. The results show that TiO2 and Fe2O3 oxides are electrochemically reduced to TiFe and Fe2Ti alloy in molten CaCl2. Direct synthesis of TiFe alloy from the mixed oxide precursors is feasible |
