摘要
高纯度无水氯化镁是电解制备金属镁的重要原料。主要论述以水合氯化镁为原料制备高纯度无水氯化镁的关键问题和国内外相应的新工艺 :(1)氯气气氛下脱水 ;(2 )复盐法 ;(3)
Highly purified anhydrous magnesium chloride is an important raw material to prepare metallic magnesium. In this article, the key problems on the preparation of high purity anhydrous magnesium chloride from hydrated magnesium chloride were discussed. Besides, some new technologies applied in domestic and abroad was mentioned, including dehydration from hydrated magnesium chloride in chlorine atmosphere, double salts (e.g. carnallite) and ammonia method.
