In this paper,a rheological phase reaction method was reported for the preparation of superfine ZnO.Firstly,the precursor was synthesized by rheological phase reaction after that the thermal decomposition of precursor in air atmosphere was studied by thermo-gravimetric and differential thermal analysis（TG/DTA）.And then the solid product of thermal decomposition was characterized by XRD（Xray diffraction）and IR（infrared）,and finally the particle size distributions and surface morphology of ZnO was studied.It proves that the particle size of ZnO distributes between 37nm and 85nm with the average size of 52nm. 氧化锌 流变相反应 尿素 ZnO rheological phase reaction urea 10.14188/j.1671-8836.2010.05.008 O614.411 湖北省教育厅基金资助项目（Q200615002） 2010-05-01 2021-04-01 5 56
