摘　　要：超声结晶是一种新的结晶分离技术,将超声应用到结晶过程可以产生显著的效果。引入超声可以缩短诱导期,促进成核,降低结晶产品的粒径;在有的体系中还会影响结晶收率,晶形,产品的流动性等。文章综述了超声结晶在无机盐、制药、食品领域的应用以及研究进展。Sonocrystallization is a new crystallization separation technology. There are significant effects of ultrasound on crystallization process. Continuous crystallization with ultrasonic irradiation results in reducing the induction time, accelerating nucleation and decreasing particle size. Nevertheless in some systems product yield, lluidity and crystal shape can be controlled by appropriate selection of the ultrasonic conditions. In this paper the application and development of sonocrystallization in inorganic salt, medicine and food fields are presented in detail.
