摘要
本文概述了超细颗粒的性质并比较了其制备方法的优缺点,从而提出一种新型的制备方法——微孔扩散技术制备法。微孔扩散技术是近年来随着膜技术的发展而迅速发展起来的一种新型的分散技术,然后对微孔扩散技术制备超细颗粒的基本原理、影响因素及其制备产物过程时的基本特征作一简述,并对微孔扩散技术的前景做了展望。
This paper summarized properties of ultrafine grain and compared the preparation method of it,thus proposed a new preparation method--preparation method using pore proliferation technology.The pore proliferation technology was a new scattered technology,which developed rapidly along with the membrane technology development in recent years,then introduce that preparation of ultrafine grain using the pore proliferation technology＇s basic principle,the influencing factor and essential feature of the process in preparating product,and pointed the prospect of pore proliferation technology.
