Abstract

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
