| 摘 要： | 以草酸和醋酸镁为原料 ,用室温固相化学反应合成出前驱配合物 ,前驱配合物在 60 0℃热分解 3h ,得到产物纳米MgO。用X射线粉末衍射、透射电镜对得到的产物进行表征。结果表明 ,固相法得到的纳米氧化镁为立方晶系结构 ,产物平均粒径为 15nm。作者以硝酸镁、碳酸钠为原料 ,用直接沉淀法合成得到纳米MgO ,平均粒径为 3 0nm。比较两种方法所得纳米氧化镁 ,固相法得到产物平均粒径比液相法小

| Abstract: | The precursor was synthesized by solid state reaction of Mg(OAc) 2·4H 2O and H 2C 2O 4·2H 2O.Nanometer MgO was obtained by decomposition of the precursor and was characterized by XRD,TEM and IR.The cubic nanometer MgO product has an average diameter of 15 nm with good homogeneity and high yield.MgO with an average diameter of 30 nm was synthesized by precipitation method with Mg(NO 3) 2·6H 2O and Na 2CO 3 as the starting materials.The average diameter of MgO by solid state reaction is much smaller than that by liquid state reaction. |
