Abstract：Based on the basic principles of biominerlization,the paper analyses calcium carbonate crystallization in waterable chitin solution under the control of chitin,using chitin as the matrix;and analyseses the effect on crystals by varying temperature or pH of the system. The obtained calcium carbonate was characterized by Fourier transform infrared spectroscopy (FTIR),scanning electronic microscopy(SEM) and X ray powder diffraction(XRD). As a result,it was found that crystals were different formed in purity water;and the obtained crystals are different in different concentration chitin solution. Calcium carbonate has effect on chitin during the calcium carbonate formation process,so there is the interaction between chitin and calcium carbonate.
