摘要
镁是地壳中含量较为丰富的金属元素,可用于助剂、添加剂与结构功能材料,有广阔的应用潜力。金属镁进入工业化生产,主要经历了电解法与热还原法,并分别衍生出各种电解法工艺与热还原法工艺。本文综述近20年国内外镁冶炼技术的研究现状,详细介绍一些典型的新型镁冶炼技术工艺,其中部分工艺方法已进入中试与产业化示范阶段,为我国原镁冶炼技术的发展起到了示范引领作用。最后,针对主流生产工艺存在的问题以及当前新工艺的研究现状,提出原镁冶炼技术发展的建议与思路。
Magnesium is a rich metal element in the earth's crust,which can be used as additives and structural functional materials.The industrial production of magnesium mainly has experienced electrolysis and thermal reduction,and various electrolysis and thermal reduction processes were derived.This paper summarized the research status of magnesium production technology at home and abroad in recent 20 years,and introduced some typical new magnesium production technologies in detail.Some processes have entered the pilot and industrial demonstration stage,which plays a leading role in the development of original magnesium smelting technology in China.In view of the problems existing in the mainstream production process and the current research status of the new process,the suggestions and ideas for the development of the magnesium production were put forward for reference.
