摘　　要：介绍了超细高活性氧化镁的主要用途,即超细高活性氧化镁吸附性强,表面化学活性高,可作为高效解离吸附剂,吸附有毒化学物质,如含氯烃、有机磷化合物和酸性气体等,用于环境保护。综述了超细高活性氧化镁的制备方法,方法有:碳酸化法、沉淀法、酸解法、微波辐射法,并比较了这些制备方法的优缺点。总结了超细高活性氧化镁的应用和研究现状,以及发展趋势。The main uses of super fine and high active magnesia were introduced.Superfine high-active MgO can be used as high-effective dissociation adsorbent to adsorb toxic chemical materials,such as chloro-hydrocarbons, organo phosphorous compounds and acidic gases owing to its high surface chemical activity and strong adsorbability.The synthesis methods of such magnesia were reviewed.The main preparation methods of superfine high-active MgO include carbonization, precipitation, acid digestion and microwave radiation.The advantage and disadvantage of all kinds of synthesis methodswere compared. The present status of application,research and development trend of such magnesia were summarized.
