氧化镁的

Metal hydroxides like aluminium trihydroxide (ATH) or magnesium dihydroxide (MDH) are commonly used halogen-free flame retardants in polyolefins.

金属物如铝（ATH）或镁（MDH）是常用的无卤阻燃体系。

Producing metal Mg with magnesia supported by electrolytical chloride is a new method and also a good method to be propitious to environment.

利用镁在氯物电解质的支持下电解金属镁是一种全新的生产方法,也是一种有利于环境保护的冶镁方法。
