| 摘 要： | 以氯化锌、尿素为原料 ,采用均匀沉淀法在一定条件下制备得到纳米级氧化锌粉体。并以TEM、SEM、XRD等测试手段对产物的粉体结构、形貌进行了研究。结果表明 ,在 2 0 0℃下热处理得到的氧化锌粉体结晶性能良好 ;在较大的反应物浓度及反应物浓度比下可以得到较小的晶体粒径 ,平均为 2 0nm ,且分散性好 ;在较小的浓度及较小的浓度比下得到的晶体粒径较大 ,并呈片状生长。阐述了浓度对于粒径大小的影响并得出片状氧化锌微晶生长的最佳条件。

| Abstract: | Nanometer ZnO was synthesized by uniform precipitation-method from ZnCl 2 and carbamide, and TEM, SEM and XRD were used to characterize the product. Result indicated that powdered ZnO with good crystal capability could be obtained after treatment at 200℃. Less granularity, bigger reactant concentration and proportion. The crystal grew in sheet, with 20 nanometers at average. Effect of concentration on the granularity, and the optimal growing condition of sheet ZnO crystals were discussed. |
