纳米级超细粉末的制备

Preparation of Nanometer-Sized UItrafines Powders

纳米级超细粉,无论是作为粉体材料,还是作为具有新型固态结构的纳米晶块状材料的基体,都有着十分重要的意义。本文结合实例,综合介绍纳米级超细粉的几种有效或有潜在可能的制备方法,其中包括近年来迅速发展的辐射分解法和超临界流体技术。

Nanometer—size Ultrafine Powders, eitheras powder materials,or as matrix of nano crystalline materials which has New —type solid state structure,is of great significance,sereral effective and possible preparation methods,including supercritical fluid technology and radiolyric syntheses developed recently are presented Compre- hensively with practical examples in this paper.
