摘　　要： 以硝酸锌和氢氧化钠为原料,三乙醇胺为表面活性剂,采用微波加热沸腾回流,在不同的反应条件下制备出了平均粒径为25～80nm的纳米级ZnO粉体。采用X射线衍射(XRD)、扫描电镜(SEM)及粒度分布仪等测试手段,对产品的物相、形貌和粒度分布进行了表征。实验结果表明,利用微波加热制备出的纳米ZnO粉体结晶性能良好,粒径大小均匀;三乙醇胺的加入,明显地改变了氧化锌的结晶行为,晶体形貌由原来的棒状变为准球形,粒径减小到纳米级。 Nanon-sized ZnO powders with particle size of 25-80 nm were prepared by a method of reflux boiling with microwave heating using zinc nitrate and sodium hydroxide as the starting materials and triethanolamine as the surfactant.The crystal structure,morphology and particle size distribution were characterized by X-ray diffractometer,scanning electron microscope and granulometer.The results showed that the ZnO nanopowders were well crystallized and evenly graded.Triethanolamine added to the system changed the crystal habit of ZnO from rod to sphere.
