| 摘 要： | 在水/乙二醇混合溶剂中,通过微波辅助加热的方法,研究溶液过饱和度对碳酸钙成核生长的影响。分别采用扫描电子显微镜(SEM)、X-射线粉末衍射(XRD)对所得的样品进行了表征。结果表明,过饱和度的改变对碳酸钙形貌和晶型具有非常明显的影响,分别获得了菱面体状方解石、纤维捆扎状文石、松树枝状球霰石为主体的碳酸钙晶体。

| Abstract: | In this paper,the influence of diffident supersaturations of the bulk solution on the nucleation and crystal growth of calcium carbonate is studied through the method of microwave-assisted heating in water/ethylene glycol mixed solvents.The obtained crystals are characterized by scanning electron microscopy(SEM) and X-ray diffraction(XRD).The result shows that the morphologies and polymorphs are obvious varied from rhombohedron calcite,fiber strapping aragonite to pine-dendritic vaterite with the changes of supersaturations. |
