X(K或Li)_3AlF_6-Al_2O_3体系低温电解研究现状评述

Commentary on the status quo of low temperature aluminium electrolysis in M(K or Li)_3AlF_6-Al_2O_3 bath system

详细概述氧化铝在锂冰晶石和钾冰晶石体系中的低温电解研究现状,系统分析各体系的优缺点,指出将来的研究方向不应该局限于单一冰晶石体系,而应该是多种冰晶石组成的复合体系,充分发挥各自优势,减少或消除弊端,最终寻找出一种低温、高氧化铝溶解度、高电导率和低铝溶解损失的新型电解质。

The status quo of the low temperature aluminium electrolysis in cryolithionite- alumina and elpasolite- alumina bath system are commended in detail, and their advantages and disadvantages also been stated with systematic analysis. The orientation of research in the future also is pointed out, it should not only one single cryolite system, but be multiple cryolite system. By this way, their respective superiority can be exhibited and inferior posi- tion can be decreased or eliminated, as a result, one new type electrolyte with low temperature, high alumina solubility, high conductivity and low loss of aluminium in it was found out.
