Solvothermal Synthesis and Characterization of Hierarchical Calcium Carbonate Spheres

Abstract:

Hierarchical calcium carbonate spheres composed of nanoparticles has been successfully synthesized via a solvothermal process. The structures are fabricated by the reaction of Ca (CH₃COO)₂ with (CO(NH₂)₂) at 110 °C in diethylene glycolwater mixed solvents in the presence of polyvinylpyrrolidone. The as-prepared products were characterized by field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD). The characterization results revealed that the average diameter of the hierarchical calcium carbonate spheres is about 5 μm, and the size of the nanoparticals range from 50 to 100 nm. In addition, a small amount of bundle-like aragonite calcium carbonate is also obtained in the experimental parameters.
