摘 要：以NH3-NH4HCO3-H2O体系中所得锌氨溶液为原料，在微波与超声波辅助及常规加热下运用蒸氨法制备活性氧化锌前驱体，考察了锌溶液浓度和蒸发温度对前驱体粒度的影响，对前驱体表征结果表明：采用微波一超声波联合辐射法制备出产物的粒度和形貌更易于控制，对制备出活性氧化锌粉体进行了SEM、X衍射及纯度分析表征，结果表明微波及超声波的加入有利于获得均匀分散、平均粒径为2.3μm，纯度可达98%以上的活性氧化锌产品．
Abstract: The influence of zinc solution concentration and evaporation temperature on the particle size of the precursor was investigated through the preparation of activated zinc oxide precursor by using the method of ammoma volatilization, which was prepared under the conventional heating assisted by microwave - ultrasound with ammoma and zinc solution got from NH3-NH4HCO3-H2O system as raw material. The characterization of precursor showed the particle size and shape of the production prepared through microwave - ultrasound method were more controllable. SEM,X- ray diffraction and purity analysis were carried out on activated zinc oxide powder. The result showed that the addition of microwave and ultrasound contributed to obtaining uniformly distributed active zinc oxide products with average diameter of 2.3μm, and product purity over 98%.
