摘　　要：A new method for mimic biomineralization was used to synthesize CaCO 3 . The organized organic substrates, which could associate with Ca 2+ by means of molecular recognition and induce the nucleation and growth of CaCO 3, were synthesized fristly, and followed by the preparation of the CaCO 3 by carbonation of a solution of Ca(OH) 2 with CO 2. Well dispersed spindle-like nano-CaCO 3 particles with an average width of 50 nm and a ratio of diameter to length about 1∶5 were obtained under the given experimental conditions. The products were characterized by FTIR spectra, TGA analysis and transmission electron microscope(TEM).A new method for mimic biomineralization was used to synthesize CaCO 3 .
