摘要
综述了高纯稀土金属的主要制备方法(如真空熔炼、真空蒸馏、区域熔炼、电解精炼、固态电迁移及联合法等)和评价手段,分析了国内高纯稀土金属研究存在的问题以及未来发展的方向。
The preparation methods including vacuum melting, vacuum distillation, zone melting, electro-re- fining,solid electro-migration and combination method, and evaluation methods of high-purity rare-earth metals are summarized. The existing problems in the respect of domestic research of high-purity rare-earth metals and its future development trend are also presented.
