| 摘 要： | 均相沉淀法制备纳米氧化锌的关键是成核与生长控制。过饱和度越大 ,成核数量越多 ,则生成的晶粒越小。成核数量与反应物浓度即Zn2 + 和OH-的浓度有关。采用尿素为沉淀剂 ,添加有机物羧甲基纤维素作分散剂以控制微小晶粒间的叠合生长 ,在温度 (130℃ )和反应时间 (2h～ 5h)下热压处理 ,制备了粒径较小、粒度分布均匀的纳米氧化锌

| Abstract: | The more dense the saturation is, the more nucleus will be formed and the smaller the crystal is. The number of nucleus formed has something to do with the density of Zn2+ and OH -. |
