摘　　要：研究采用水/Tritonx-100/苯/正丙醇微乳液体系,水/正丁醇共沸体系进行干燥,煅烧制备出纳米ZrO2粉体,用X射线粉晶衍射(XRD)检测ZrO2的相态,扫描电镜(SEM)和透射电镜(TEM)检测ZrO2粉体的粒度,石墨炉原子吸收(GFAAS)检测ZrO2粉体中Al的掺杂率。制得的粉体团聚程度低,粉体的粒度分布在10～100nm之间,粒度分布均匀,形状一致,Al的掺杂率达到95%。Microemulsion system is a good system to synthesis nano-sized particles, for it can control the shapes and granularity of nano-sized particles and other elements can be easy doped. In this research the water/Tritonx-100/benzene/propanol system is used. The colloid is washed and calcined at different temperatures. The Azeotropic distillation method is used to dry the colloid. The XRD, SEM, TEM and GFAAS are used to characterize the Zirconia powders. The dope ratio of Al2O3 can get 95%. The size of Zirconia particles is 10-100nm.
