摘要
采用溶胶-凝胶法,以六水氯化镁和氨水为原料,以聚乙二醇(PEG)为改性剂进行了纳米氧化镁的改性研究,并用X-射线衍射仪(XRD)和透射电子显微镜(TEM)及比表面分析仪(ASAP2020)对产物进行了表征。结果表明该方法制备的纳米氧化镁具有粒径小、比表面积大和热稳定性好的特点,PEG不但控制了纳米氧化镁粒子的形状和大小,还使粒子的结晶度、分散性提高,并且基本上无团聚现象。
In this paper, Sol- Gel method was used to produce nano- magnesiam, using MgCl2 ·6H2O and ammonia liquor as the raw material. The gels were treated in fluid N2. The surface area of samples were characterized by ASAP- 2020, X- ray diffraction （XRD） and Transmission Electron Microscopy（TEM）.The result of experiment showed that grain size of nano- magnesia was small and surface area was large and stability of heat was good .
