采用固体透氧膜（solid oxygen-ion membrane，SOM）熔盐电解法，对含钛复合矿直接脱氧并选择性提取钛合金.经过X-射线衍射（X-ray diffraction, XRD）、扫描电子显微镜（scanning electron microscope, SEM）和能量分数X-射线（energy dispersive Xray, EDX）分析，结果表明：从含钛高炉渣中可以直接提取出Ti5Si3合金粉末，并可有效去除金属杂质Ca，Mg，Al；从钛铁矿中可以直接提取出TiFex合金.最后，对电解脱氧过程进行讨论分析.

Direct deoxidization of Ti-bearing compounds was done by using solid oxygen-ion membrane (SOM) molten salt electrolysis and selective extraction of titanium alloys simultaneously. X-ray diffraction (XRD), scanning electron microscope (SEM) and energy dispersive X-ray (EDX) analyses show that the Ti5Si3 alloy can be extracted directly from Ti-bearing blast furnace slag. Metallic impurities such as calcium, magnesium and aluminum were completely removed from products during electrolysis. In addition, TiFex alloys can also be obtained directly from deoxidized ilmenite (FeTiO3) in molten salt. Finally, the electro-deoxidation processes are discussed.〖HJ〗
