摘　　要：以草酸和氯化镁为原料,采用固液法制备了纳米级氧化镁粉体。优化了试验条件,并用TEM和XRD对纳米氧化镁的粒子结构和形貌进行了研究。结果表明,在600℃焙烧,得到的纳米氧化镁粒度分布均匀,平均粒径为15 nm。并对固液法生成纳米氧化镁的机理进行了初步探讨。Nano - MgO is prepared by Solid - liquid method with（COOH）2 · 2 H2O and MgCl2 · 6 H2O as raw materials. Microstructure and morphology of nanometer - size MgO are investigated by means of TEM, XRD and FT - IR. The results show that well - distributing nanometer - size MgO particles are prepared at calcining temperature of 600 ℃. The average size of the particles is 15 nm. The reaction mechanism of nano - MgO formation is also discussed.
