超临界流体快速膨胀法制备微细颗粒

The preparation of minuteness particles by rapid expansion of supercritical fluid solutions

利用超临界流体快速膨胀法(RESS)制备微细颗粒,是近年来兴起的一种很有应用前景的新的粉体技术。笔者就该技术的过程原理、典型实验装置、过程条件的影响因素、近年来国内外的主要研究成果及其存在的问题进行了论述。

Using the technique of the rapid expansion of supercritical fluid solution,is a recent development, which is a novel and useful technique for preparing small particles. This paper discussed the fundamental principles, typical experiment apparatuses, influence factors ,application researches and some problems of the rapid expansion of supercritical technique briefly.
