选择性审查阳极和阴极过程与电解提取，电解精炼和电镀的难熔金属（钛，锆，铌和钽）从熔融盐为基础的电解质方面在过去的二十年中获得的结果。特别注意的是阴极还原和它的限速步骤，以及平行的化学反应的反硝化和络合的机制。讨论了钛、锆、铌和钽在熔融电解液中腐蚀和电溶解的阳极过程。最后，提出了一些与学科相关的矛盾问题，并提出了一些新的研究方向。
A selective review of the anodic and cathodic processes associated with electroextraction, electrorefining and plating of refractory metals (Ti, Zr, Nb and Ta) from molten salt-based electrolytes is presented with regard to the results obtained during the last two decades. Special attention is paid to the mechanism of cathodic reduction and its rate-limiting steps, as well as to the parallel chemical reactions of disproportionation and complexing. The anodic processes in corrosion and electrodissolution of Ti, Zr, Nb and Ta in molten electrolytes are also discussed. As a conclusion, a few contradictory subject-related questions are outlined and some new trends of investigation are suggested.
