| Abstract: | Calcium carbonate(CaCO3) ultrafine particles with different morphologies, including chain like, flake, rod, rhombohedral, spherical and hollow spherical were successfully synthesized by a controlled precipitation method. The products were characterized by powder X ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM). The main factors to influence the crystal structures and morphologies of CaCO3 in preparation process are discussed, which is helpful to understand the crystal nucleation and growth of CaCO3 ultrafine particles. |
