Abstract: A new method for mimic biomineralization was used to synthesize CaCO3 . The organized organic substrates, which could associate with Ca 2+ by means of molecular recognition and induce the nucleation and growth of CaCO3, were synthesized fristly, and followed by the preparation of the CaCO3 by carbonation of a solution of Ca(OH)2 with CO2. Well dispersed spindle-like nano-CaCO3 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).

Key words: Biomineralization, CaCO3 nanoparticle, Synthesis in situ, Organic substrates, Spacial framework
