摘要
对超临界流体用于制备超细粉体的研究现状和主要研究成果进行了综述。介绍了近年来开发的一些新方法和新工艺 ,其中包括超临界溶液快速膨胀 (RESS)法 ,超临界流体脱溶 (SAS)法 ,超临界逆向结晶 (SRC)法 ,超临界干燥 (SD)法和超临界流体化学反应等。分析了这些新工艺新方法的原理、特点 ,技术上的可行性 ,应用前景 ,目前达到的水平与存在的问题 ,及今后发展需解决的关键问题等。
The status of research and major achievements in the research of micropowder formation with supercritical fluids were reviewed.Some new methods and processes developed recently were introduced including methods of rapid expansion of supercritical solutions(RESS),supercritical anti solvent(SAS),super critical retrograde crystallization(SRC), supercritical drying(SD),and chemical synthesis of supercritical fluids,etc.The principles,features feasibility,application prospect,present level and existing problems,and the key problems which needed solving for further developing of the new methods and processes were analyzed.
