摘要：  难熔金属及合金的制备一直以来是一个耗能、复杂且困难的冶金及材料制备过程。如何从复杂高熔点金属氧化物矿物中直接提取获得高价值金属及合金，是新时代冶金及金属材料制备领域的研究重点和难点之一。近年发展起来的新熔盐电脱氧技术，可望对这一困境带来解决途径。笔者对“传统”熔盐电解法制备难熔金属进行了回顾，分析其面临的难题；对Fray-Farthing-Chen(FFC)剑桥法为代表的新熔盐电脱氧方法进行介绍，并重点介绍和展望了本课题组改进的固体透氧膜(SOM)法在该领域的发展和前景。

Abstract: The production of refractory metals and alloys has always been a high energy costs, complex and difficult metallurgical and materials processing process. How to extract the high-value metals and alloys direct from complex refractory metal oxides compounds is a very important and difficult research focus in the fields of modern metallurgy and materials preparation. However, the new electro-deoxidation technology developed in recent years may bring a route to this unsolved problem. In this paper, we review the conventional molten salt electrolysis process for production of refractory metals and analyze its shortages. Moreover, the
new electro-deoxidation process, i.e., the Fray-Farthing-Chen (FFC) Cambridge process is introduced in detail. In particular, the research progress and prospect of the solid oxide membrane (SOM) process modified by our group are presented and highlighted in this paper.

Key words: molten salt electrolysis, refractory metal, alloy, solid oxide membrane
