| 摘 要： | 依据仿生矿化的基本原理以菊糖作为有机基质以CaCl2为钙源,NH4HCO3为CO2来源,采用气体扩散的方法合成了花束状并且具有分级结构特征的碳酸钙,对所得产物进行了XRD,SEM,FTIR和TG-DTA表征.结果表明,菊糖水溶液中得到的为方解石和球霰石的混合晶型的CaCO3.进一步机理研究表明菊糖在CaCO3形貌的形成过程中起着重要的作用.

| Abstract: | Based on the principles of biomineralization,a simple gas diffusion method was adopted to synthesize the flower-like calcium carbonate in the water solution of synanthrin.The products were characterized by XRD,SEM,FT-IR and TGDTA.The results revealed that the products represented a mixed crystal type,and were consisted of calcite and vaterite.Further study exhibits that synanthrin played a critical role in the formation of the hierarchical flower-like calcium carbonate and its crystal type. |
