Preparation and Characterization of Twin Spherical Calcium Carbonate by the Direct Mixing Precipitation Method

Abstract

Abstract: The well dispersed twin spherical CaCO3 particles with granular size of 1.5—3.0 μm and a ratio of length to brachyaxis about 2∶1 were prepared directly via a liquid mixing precipitation method in the presence of trisodium citrate, using calcium acetate and sodium calcium solution as raw materials. The obtained CaCO3 samples were characterized by means of scanning electron microscope(SEM), X-ray diffraction(XRD), Fourier transform infrared spectroscopy(FTIR), thermogravimety analysis(TG), atomic force scanning probe microscopy(ASPM) and size analysis. The results show that twin spherical CaCO3 particles with different crude surface degree are obtained in the presence of mass fraction of trisodium citrate 30%~40%, whereas, only cubic micron CaC03 crystals are obtained without trisodium citrate. The formation mechanism of twin spherical CaCO3 was analyzed by the fractal growth theory and the nucleation limited aggregation(NLA) model at the same time.
