【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。更多还原

【Abstract】 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.更多还原
