Biomineralisation is the synthesis of minerals from simple compounds by organism.
Calcium carbonate (CaCO3), one of the most abundant biominerals, is found as different
polymorphs of calcite and vaterite.
In the study, crystallization of calcium carbonate using aqueous calcium chloride and sodium carbonate at room temperature was performed. The polymorphic control of crystalline calcium carbonate was achieved by adjusting the operating conditions.
Calcium carbonate crystals were nucleated with silk amino acids. Silk amino acids were
used as effective modifiers to mediate the crystallization of CaCO3. The obtained crystals
were characterized by scanning electron microscopy(SEM), Fourier transform infrared
spectroscopy(FT-IR) and X-ray diffraction(XRD).
