摘 要: 超临界流体结晶技术是一种新的发展前景很好的超细颗粒制备技术。本文论述了它的特点和结晶过程的两个重要路线 :超临界流体快速膨胀结晶法、超临界流体抗溶剂结晶法。同时综述了近年来超临界流体结晶技术的应用研究情况 ,指出了该技术存在的问题和应用前景。 The use of supercritical fluids as a media for the formation of ultra-fine powered materials is a recent development with a good prospect. After a presentation of characteristics of this technique and fundamentals of crystallization, this paper describes two routes to particle formation: the rapid expansion of supercritical fluids and the supercritical antisolvent. The research on application is reviewed, and their problems and prospects are also pointed out in this paper.
