摘　　要：以氯化镁和草酸为原料,分别以淀粉和聚乙二醇1000为分散剂,采用低温固相法制备出不同形貌的纳米氧化镁。采用IR、TG-DTA、XRD和TEM分别对产物形貌和粒径大小进行了表征。结果表明,分散剂的种类和用量是影响纳米氧化镁颗粒大小和均匀度的重要因素。Nano-sized MgO were prepared by a solid-state method at lower temperature using MgCl2 · 6H2O and H2C2O4·2H2O as raw materials and soluble starch and PEG1000 as dispersing agents. The particle size and morphology of nano-sized MgO were investigated by IR,TG-DTA, XRD and TEM. The results indicate that the species and using level of dispersing agent were important factors to the particle size and distribution of the nano powder.
