摘要

以工业Al(OH)3为原料

用沉淀法制备纳米Al2O3粉体.探讨了制备过程中前驱体表面电位ζ与洗涤分离的条件在分离过程中对过滤速度的影响

发现采用去离子水洗涤后

粉体的ζ电位明显降低

接近其等电点

从而导致洗涤速度变慢.使用0.1 mol/L稀氨水取代蒸馏水

随着pH值的增大

ζ电位提高

过滤速度加快.取得了适宜的工艺条件.用X射线衍射仪(XRD)、透射电镜(TEM)和粒径分析仪

对实验所得粉末的结构进行了表征.结果表明:所得粉体粒径为59.3 nm的α-Al2O3

形貌为纤维状

并且分散好、粒径均匀.

Abstract

With industrial Al(OH)3 as the raw material

preparing nanometre α-Al2O3 powders by precipitation method

it was investigated that the influence of ζ surface potential of the precursor and the separation condition of gel aluminum hydroxide on the speed of the filtration in the process of separation.And it was found that

by the adoption of distilled water

the ζ potential of the powder was obviously decreased close to its isoelectric point to make the filter velocity slower.When the 0.1 mol/L ammonia was used to take the place of distilled water

pH value and ζ potential were increased

and the filter velocity becomes quicker as well.Thus the favorable technical condition was obtained.Then TEM and XRD were used to characterize the powder's particle shape and size distribution.Results show that the powders obtained is fibrous

dispersive and epigranular α-Al2O3

whose average particle diameter is 59.3 nm.
