熔盐电解制备难熔金属的回顾与展望

his 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. The new electrolysis processes open up a new field for producing refractory metals with low cost and have a good future.
