摘　　要：以硝酸锌为原料,采用溶胶—凝胶/燃烧合成结合法制得了氧化锌超细纳米粉体。用X射线衍射仪确定了不同温度热处理粉体的相组成,由扫描电子显微镜观察粉体的形貌。氧化锌的特征峰在400℃就已形成,随着温度的升高,衍射峰的强度逐渐增强,经600℃热处理粉体的粒径达到50 nm左右。Zinc oxide （ZnO） powders were synthesized by a sol-gel combustion process from a solution zinc nitrate. XRD techniques were used to characterize the processed precursor and ZnO powders calcined at different temperatures. The particle sizes were characterized by scanning electron microscopy （SEM）. It was found that the ZnO phase to nucleate directly from the processor at about 400%. When the temperature is elevated to 900℃, high and sharp peak is observed. The powders calcined at 600℃ is about 50 nm.
