Abstract
Crystallization of calcium carbonate was performed by using aqueous calcium chloride and sodium carbonate for operational simplicity. Reaction time, solute concentrations, pH, and organic additive were varied to get calcium carbonate crystals. Silk fibroin was used as the additive to understand the change of morphology of calcium carbonate crystal. The crystals were analyzed by FE-SEM, XRD, and FT-IR. Reaction time, and pH mainly affected the morphology of crystals. Besides, it was found that silk fibroin inhibited the formation of vaterite and promoted the calcite forms.
