以硝酸锌、尿素为原料, 采用均匀沉淀法制备纳米氧化锌粉末. 以TEM和BET等方法对产物进行了表征, 发现可获得50nm左右的纳米氧化锌, 粒子
的比表面积为25.6m2/g; XRD分析表明, 产物为六方晶系; 通过XRD、IR和TG-DSC分析, 确定了纳米氧化锌的形成机理.
Nanometer ZnO particles were synthesized by the homogeneous precipitation method from urea and zinc nitrate. TEM analysis shows that nanometer ZnO particles obtained are in the
nanosize range of 50nm; BET analysis shows that the specific surface area of the ZnO particles is 25.6m2/g; XRD analysis shows the crystalline
of the nanometer ZnO particles is in the hexagonal structure; the formation mechanism of nanometer ZnO particles was concluded by the analysis of XRD,
IR and TG-DSC.
