摘要:综述了化学因素(溶剂和添加剂等)和工程因素(过饱和度,晶种和搅拌等)对溶液结晶中晶体形态与结构的影响,分析了这些因素会影响溶质分子在溶液主体中的聚集形式及其在晶体界面的扩散和吸附过程,进而影响晶体的成核和生长机理及速率,并由此改变最终产品的形貌和结构。调控结晶工艺参数和优化操作条件可得到目标结晶产物。
In this work,effects of the chemical factors(solvents,impurities,and additives) and engineering factors(supersaturation,crystal seeds and agitation) on crystal morphology and structure were discussed,respectively.The two factors could affect the aggregation state of solute molecules in solution and its diffusion/adsorption processes on crystal interface,which further resulted in effects on nucleation and crystal growth mechanisms and kinetics.Eventually,the crystal morphology and structure of final crystals were changed.The crystals with desired morphology and structure could be obtained by optimizing the operation conditions.
