摘要
通过添加剂调控制备形貌各异、结晶良好的半水石膏晶体备受关注。简述了有机添加剂、无机添加剂及复合添加剂调控半水石膏晶体生长成纤维状石膏晶须或短柱状高强α石膏的研究现状;总结并评述了有机、无机两类添加剂对半水石膏晶体成核和生长过程的调控机制;分析了该领域亟待深入研究的问题,为半水石膏晶体及同类晶体材料的结晶生长控制提供了参考。
The preparation of hemihydrate gypsum crystals with different morphologies by using additives has attracted much attention.Recent research work on the use of organic,inorganic and composite additives to control the growth of hemihydrate gypsum crystals into fibrous gypsum whiskers or short columnar high-strengthαgypsum was summarized.The regulation mechanism of organic and inorganic additives on the nucleation and growth process of hemihydrate gypsum crystals was represented.Some problems that need to be further studied in this field were analyzed.This review can provide a reference for the crystal growth control of hemihydrate gypsum crystals and similar crystal materials.
