超重力法制备纳米氧化锌的影响因素及其机理

Influential factors and mechanism in preparing nanometer zinc oxide by rotated packed bed

通过一系列实验,研究了超重力法制备纳米氧化锌的影响因素,如反应最终pH、反应料液的初始浓度、反应物氨气和锌盐溶液之间的流量比、氢氧化锌的煅烧时间与温度、洗涤反应最终悬浮液的终点、反应最终料液的陈化时间等等对纳米氧化锌性能的影响,制备出了外观为棒状和球形的两种纳米级氧化锌。并详细地探讨了其机理。

Nanometer zinc oxide was prepared with rotated packed bed (RPB). The influential factors are studied, for example, pH of the end of reaction, initial concentration of reactive liquid, ratio of reactive materials, the temperature and time of calcining of Zn(OH)2 the end of washing zinc hydroxide, etc. Rhabdoid and spherical zinc oxide was prepared. Moreover, the mechanism was analyzed in detail.
