| 摘 要： | 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 X ray, 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.

| Abstract: | 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 a... |
