制备条件对Al(OH)_3超细粒子尺寸及分布的影响

Influence of Preparation Conditions on Particle Size Distribution of AI(OH)3 Ultrafine Powders

采用化学沉淀法制备了Al(OH)3超细粒子,用扫描电镜(SEM)和粒度分析法对颗粒尺寸进行观察和测定,并研究了制备条件对Al(OH)3超细粒子粒度及其分布的影响.实验结果表明:反应物初始量浓度、反应温度、陈化时间及表面活性荆的加入是影响产物Al(OH)3粒子尺寸及分布的主要因素.

A1(OH)3 ultrafine particle were prepared by chemical precipitation method.TEM and particle size distribution techniques were employed for the observation and measurement of primary particle and grain size, and the influence of preparation conditions on particle size distribution of A1(OH)3 ultrafine powders has been investigated.
