| 摘 要： | 以硝酸镁和硬脂酸为原料,用溶胶—凝胶(Sol-Gel)法制备得到了纳米氧化镁微粒,并用热重(TG)分析、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形貌进行了表征。结果表明,控制Mg(NO3)2和CH3(CH2)16COOH物质的量比为1∶4,在90℃反应20 min并于360℃热处理4 h,得到立方相氧化镁纳米微粒,形貌为椭球体,分散性好,平均粒径约为33 nm。

| Abstract: | In this research,MgO nanometric powder was prepared from Mg(NO_3)_2 and stearic acid by Sol-Gel method.Its structure and quality had been studied by IR spectra,TG,DSC,XRD and TEM.The experiment results showed that the cubic nanometric MgO powder of good dispersion could be obtained.Its shape was ellipsoidal and average diameter was 33nm,under the optimum conditions. |
