| 摘 要： | 当粉体的尺度达到纳米级时,就会有独特的性能和广泛的应用。但是由于其较小的粒度,因此在制备和应用的过程中容易发生团聚。本文中对超细粉末的团聚机理进行了介绍,同时分析了液相法制备超细粉体过程中团聚形成的原因,以及团聚程度的表征和减少团聚的方法。另外对今后的发展方向提出了一些建议。

| Abstract: | When the particle size of powder decreses to nanoscale, it has many novel properties and therefore has numerous application. However,the agglomeration is caused easily in the process of preparation and application because of its higher surface energy. The mechanism and characterization and countermeasures of the agglomeration of ultra-fine particles prepared from wet-chemical precipitation are presented. In addtion,the suggestions were proposed for the future development of nano-technology. |
