| Abstract: | Using zinc nitrate as the starting material and ammonia and urea as precipitating agent,we prepared nano-ZnO powder by direct precipitation method and homogeneous precipitation method. The effects of the reactants concentration and mixing ratio, the types and the concentration of surfactants on the powder diameter were discussed. The nanometer powder was characterized by TEM, XRD and DSC-TG. The results showed that homogeneous precipitation method is superior to direct precipitation method and adding surfactants is useful to improve powder reuniting. |
