前言我国目前使用的99.99％结晶状高纯镁,一般系采用真空升华法或真空蒸馏法生产。高纯镁主要用于某些稀有金属还原剂,少量用做配制镁合金及制取高纯镁粉等。因生产方法不同,某些杂质在产品中含量也略有差别。本文根据我国十多年高纯镁生产实践,对真空升华 Preface The 99.99% crystalline high purity magnesium currently used in our country is usually produced by vacuum sublimation or vacuum distillation. High purity magnesium is mainly used for some rare metal reductants, a small amount for the preparation of magnesium alloy and preparation of high purity magnesium powder. Due to different production methods, some impurities in the product content is also slightly different. This article according to China more than ten years of high purity magnesium production practice, the vacuum sublimation
