| 摘 要： | Spherical calcium carbonate was prepared by the reaction of sodium carbonate with calcium chloride at the presence of a protein-like molecule， polyvinylpyrrolidone， as the template. The products were characterized by elemental analyses， XRD， SEM， and TG-DSC respectively. The effects of polyvinylpyrrolidone on the crystal form and morphology of the as-prepared CaCO3 were investigated. It was found that the aggregative shape of the produced calcium carbonate crystalline could be well controlled by adjusting the concentration of the polyvinylpyrrolidone template. This may be of important meanings to the biomimetic synthesis of novel inorganic materials.
