Character、application and preparation of nanometer sized particles and nanocomposite

本文介绍了纳米粒子的一般概念、特性及本质根源。纳米粒子因其特异的性能在高科技领域得到了日益广泛的应用。文中对纳米材料现有的应用及其前景作了简要的介绍，并综合评述了目前国内外制备纳米粒子的常用方法，综述了引起粒子间团聚的机理和后处理过程中有效地防止团聚的方法。

General conception and aspects nanometer sized particles, novel characters and properties of ultrafine powder were reviewed. For their excellent characters, nanmoeter Sized particles had been widely applied, especially in Hi-Tech fields. The application and attractive of some nanometer material and nanocomposite.were also described here. Common methods for preparing nanometer sized particles and the mechanism leading to agglomeration of particles had been reviewed, and the rout for diminishing and preventing agglomeration were introduced.
