| Abstract: | Based on the basic principles of biomineralization,in the ethanol/water system,a CaCO3 with spherical morphology is synthesized under the control of tryspin by the gas diffusion method.The obtained CaCO3 are characterized by XRD,SEM and FT-IR.The results indicate that the CaCO3 crystal is the compound of calcite and vaterite,and that during the CaCO3 formation process,the tryspin has controlled the morphology of CaCO3 mainly.Furthermore,the ratio of ethanol/water solution also has some impact on the formation of the morphology. |
