稀土元素合金的制取方法制取镝、铽之类重稀土类金属的传统方法，是用钙还原法或者是采用铁等作自耗电极进行熔盐电解制取稀土金属－铁（Ｒ－Ｆｅ）合金的方法，但这些方法生产成本都较高而且操作复杂。为改善其生产工艺，日本信越化学工业公司提出了一项制取稀土金属元素... Preparation of rare earth alloy The preparation of dysprosium, terbium and other heavy rare earth metals, the traditional method is to use calcium reduction method or the use of iron as the consumable electrode for molten salt electrolysis Preparation of rare earth metal - iron (R- Fe) alloys, these methods are expensive to produce and complex to operate. In order to improve its production process, Shin-Etsu Chemical Co., Ltd. made a preparation of rare earth metal elements ...
