摘　　要：以氯化镁和氨水为原料,用直接沉淀法制备了纳米氧化镁微粒,并用热重分析(TG)、X射线粉末衍射(XRD)、红外光谱(IR)和透射电镜(TEM)等对该纳米微粒的结构与性能进行了表征.结果表明,所得纳米氧化镁微粒呈立方晶型,形貌为椭球体,分散性好,粒径在15～45 nm之间.MgO nanometer powder is prepared from MgCl2 · 6H2O and NH3 · H2O by direct precipitation method. Its structure and property are characterized by IR spectra, TG, XRD and TEM. The results show that the cubic nanometer MgO powder with good dispersion can be obtained, and its shape is globular and diameter is between 15 -45 nm.
