摘要
以镀锌厂含铁锌渣和碳酸钠为原料,先后加入离子型和非离子型表面活性剂,在超声波搅拌的作用下,用化学沉淀法制得淡黄色纳米氧化锌粉体,用XRD,TEM,S_(BET)等方法分别对产品的粒径、颗粒形状及晶形结构等进行检测。结果表明,所得产品为六角相氧化锌,平均粒径约25nm,外观近似球形,分散性较好。
Hard zinc from thermo plating zinc factory was treated for preparation of ZnO
nanometer powder by chemical precipitation. It is very important in preparing process that
ion--and non--ion type surface--active reagents are added in steps and agitated under ultrasonic
condition. Thermo--decomposition temperature of the precursor is determined to be about
450 C by TG/DTG (thermal gravity/differential thermal gravity). The obtained ZnO prod-
uct is light yellow powder. The ZnO powder is characterized by XRD, S_(BET)(BET specific
surface area analyzer), and TEM (transmission electron microscopy). The results show that
the product is sphere particles with good disperse, and the average diameter of the particles
is approximately 25 nm. The crystal is pure ZnO With hexahedral structure.
