摘 要: 对传统熔盐电解法制备难熔金属进行了回顾,分析了其中不成功的原因,介绍了新的熔盐电解法—FFC法(FFC即在氯化钙熔池中电解还原固态氧化钛制取金属钛)和固体氧化物膜(solid oxide membrane,SOM)法,并对上海大学提出的一种改进的SOM法在制备Ti,Ta,Cr方面的成功应用进行了重点介绍,同时对熔盐电解在处理钛渣及复合矿的应用前景方面进行了展望。新的熔盐电解法为熔盐电解制备难熔金属方面开辟了一个新天地,是难熔金属发展的可行之路,同时也为国内复杂矿物资源综合利用提供了一条全新思路。
关 键 词: 有色金属冶金;难熔金属;综述;熔盐;FFC法;SOM法

Abstract: This paper reviews the conventional fused salt electrolysis process for production of refractory metals and analyzes its shortages. New fused salt electrolysis processes such as FFC process and SOM process are introduced, especially, introducing a modified SOM process proposed by Shanghai University which succeeds in extraction of refractory metals such as titanium, tantalum and chromium directly from their respective oxide, and as well introducing the prospect of new fused salt electrolysis process for extracting titanium or its alloy from Ti-bearing blast furnace slag and ilmenite. The new electrolysis processes open up a new field for producing refractory metals with low cost and have a good future. It proposes a new idea for comprehensively utilizing the complex mineral resources.
Key words: nonferrous metallurgy; refractory metals; review; fused salt; FFC process; SOM process
