利用固体透氧膜（SOM ）法直接由含钛渣还原制备金属钛及其合金。将粉态含钛渣压片制成阴极，以YSZ管内碳粉饱和的铜液为阳极，以1100℃电解温度、3．5 V槽电压在CaCl2熔盐中电解，研究成型压力及电解时间对电解产物的影响，分析电解过程中的杂质行为。结果表明，随电解时间的延长，电解产物中的钛、铁含量不断增大，产物颗粒形貌趋于匀细疏松；对于铁钛渣，电解6h可获得钛铁合金；对于高钛渣，成型压力为3MPa时，电解4h可除去氧，电解6h可获得纯金属钛；较小成型压力下的多孔阴极有利于杂质元素的去除。

Ti and Ti alloy were prepared by solid oxygen-ion membrane (SOM ) process from Ti-bear-ing slag directly .Ti-bearing slag powder was pressed into pellets and then employed as the cathode , and carbon-saturated liquid copper loaded in YSZ tube was used as the anode ,which were electrolyzed in molten CaCl2 at 1100 ℃ with a potential of 3 .5 V .The influence of forming pressure and electro-lytic time on electrolytic products was analyzed .The results show that Ti and Fe increase in content with electrolytic time ,whose morphology develops towards even ,fine and loose .Ti-Fe alloy can be obtained from Ti-Fe slag after electrolysis for 6 h ,and for Ti-rich slag ,when the forming pressure is 3 MPa ,electrolysis for 4 h can remove oxygen completely and for 6 h ,yield pure Ti .Under small forming pressure ,the porous cathode helps remove the impurities .
