摘要：

熔盐电解法是一种高效制备镁稀土合金的方法,工艺流程简便易于连续生产,而且制备的镁稀土合金成分均匀,不偏析。不同稀土元素的熔盐体系也有所区别,重稀土元素一般采用氧化物电解法,而轻稀土元素则采用氯化物电解法。针对以上不同的电解方法,本文从电解原料、电解槽结构、电极过程、电解工艺、尾气处理等多方面详细阐述了制备镁稀土合金的现状,并对电解法制备镁稀土合金的未来提出发展方向。

关键词: 氟化物熔盐, 氯化物熔盐, 电解法, 镁稀土合金

Abstract:

It is a high efficient method to prepare Mg-RE(rare earth) alloys in molten salt electrochemical process for its easy mass production and simple procedure. The RE element distributes uniformly and continuously in prepared Mg alloys. The heavy and light RE elements are extracted by electrolyzing from fluoride fusion and chloride fusion, respectively. Recent advances in preparation of Mg-RE alloys in molten salt electrochemical process are elaborately discussed from materials, electrolytic tank, electrode process, technical parameters and anodic gas absorption, and some beneficial advices focused on future developments about preparation of Mg-RE alloy are indicated.

Key words: fluoride molten salt, chloride molten salt, electrolysis, Mg-RE alloys
