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。 Using zinc nitrate as raw material, ultrafine zinc oxide powder was prepared by sol-gel / combustion synthesis method. The phase compositions of heat-treated powders at different temperatures were determined by X-ray diffractometer. The morphology of the powders was observed by scanning electron microscopy. The characteristic peak of zinc oxide has been formed at 400 ℃. With the increase of temperature, the intensity of the diffraction peak gradually increases, and the particle size of the powder after heat treatment at 600 ℃ reaches about 50 nm.
