无机盐晶体形貌调控研究进展
|
摘要
多晶形无机盐在石油化工、食品加工、医药、机械建筑和功能性材料方面的广泛应用前景使得无机盐晶体形貌的调控成为研究热点。影响无机盐晶体形貌的操作因素,可以按照调控途径分为化学因素和过程因素。其中化学因素有溶剂和添加剂,而过程因素则包括过饱和度、温度、外场(如磁场、超声波场等)、搅拌以及晶种等。主要概述了无机盐溶液结晶过程中影响晶体形貌的相关理论研究,如晶体生长的扩散学说,晶体的层状生长和螺旋位错生长等,并为今后无机盐的晶形调控提供了参考基础和指导。
The widespread application prospect of polymorphic inorganic salt in petrochemical industry,food processing,medicine,mechanical construction and functional materials makes the research of inorganic salt crystal morphology become a hotspot.Influence factors impacting the crystal shape of inorganic salt are recognized from chemistry and course of crystallization totally.The chemical factors are solvent and additives(impurities),while the process factors include supersaturation,temperature,external field(such as magnetic field,and ultrasonic),agitation and seeding.The related theoretical research on the crystal morphology control of salt in solution crystallization,such as the diffusion-reaction theory,the layered formation of crystal and the screw dislocation form,were mainly introduced,as well as a reference basis and guidance for the future crystal control of inorganic salts were provided.
