摘要:

溶液结晶是晶体培养与工业生产中的重要流程。本文介绍溶液结晶的基本原理与过程,突出过饱和度的概念,探讨影响溶液结晶的重要因素,并基于影响过饱和度的单一或复合变量综述常规与新兴的溶液结晶方法与技术,包括其基本原理与操作、典型案例等内容。最后,基于5W1H法对溶液结晶下晶体培养过程的优化设计进行讨论。

关键词: 溶液结晶, 晶体培养, 过饱和度, pH, 剪切流

Abstract:

Solution crystallization is an important process in crystal growth and industrial production. In this review, the basic principle and process of solution crystallization method were introduced, in which the concept of supersaturation was highlighted, and several factors influencing this process were put forward. Furthermore, a collection of conventional and emerging methods and techniques of solution crystallization were summarized based on the single or composite factors affecting solution supersaturation, including their basic experimental principles, operating procedures and typical cases of the application. Finally, the optimal design of crystal process under solution crystallization was discussed using 5W1H method.

Key words: Solution crystallization, Crystal growth, Supersaturation, pH, Shear flow
