摘 要: 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 25.6m^2/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.
