摘要:

采用鼓泡法,以聚乙二醇(PEG)为有机质,制备出粒度分布较均匀、由立方状纳米粒子聚集而成的棒状方解石型碳酸钙。实验结果表明,PEG在反应中控制了产物的形貌和粒径。通过改变反应温度、PEG用量等考察了反应的最佳条件,同时通过FESEMTEMXRDFTIR和粒度等测试手段对产品的结构和性能进行了表征。

Abstract:

In this paperthe rod-like calcium carbonate particles were prepared by a bubbling method. The particles with uniform granularity were gathered by cube particles when PEG was used as the organic matrix in the reaction. The results revealed that the morphology and size of the rod-like calcium carbonate were controlled by PEG. The best condition was studied by reaction temperature and the dosage of PEG. At the same timethe product structure and properties were characterized by FESEMTEMXRDFTIR and size distribution.
