摘 要: 首次在微波场作用下,采用直接法和间接法快速合成了氟化铈(Ⅲ),通过XRD、TG-DTG及场发射扫描电镜(FE-SEM)等方法对样品的组成、结构进行了分析表征,并讨论了两种合成方法以及微波合成条件对产物的影响。研究表明:采用本方法合成的CeF_3,晶型为类球形,平均粒径约为100nm。 Nanostructure cenum(Ⅲ) fluoride was synthesized by two ways in microwave radiation field.The samples were characterized by XRD,TG-DTA and FE-SEM.The effect of these two methods and reaction conditions in microwave radiation field were discussed.The results show that nanostructure cerium fluoride with a spherical morphology at a crystalline particle diameter of about 100nm was obtained.
