Biomineralization of calcium carbonate was studied in the solution containing aspartic acid (Asp). Peristaltic pump controled feeding velocity of Asp or Na2CO3 solutions. Morphology and growth of crystals were varied by changing feeding velocity of Asp or Na2CO3 solution into CaCl2 solution. The ratio of calcite and vaterite crystals was observed in accordance with the reaction time. CaCO3 crystals were analyzed by X-ray Diffraction (XRD), Field Emission Scanning Electron Microscope (FE-SEM) and Fourier Transform Infrared Spectrometry (FT-IR). XRD was used to select the intensities and crystal structure of specific calcium carbonate. SEM was employed for the analysis of the morphology of the precipitation and particle size. Two kinds of crystals were identified by FT-IR spectrum. Vaterite morphologies were affected by the Asp in the crystallization solution. Excess amount of Asp induced vaterite morphologies. Various morphologies of CaCO3 were made by changing feeding velocity of Asp and Na2CO3 solutions.
