| Abstract: A conventional vapor diffusion method was applied to in vitro precipitation of CaCO3 crystal. The morphologies and components of the deposit were characterized by SEM, Raman and X-ray diffraction. The results show that the surface of shell nacre promotes the nucleation of aragonite polymorphs of CaCO3, while suppresses the nucleation of calcite and vaterite. The active sites for the deposit, which subsequently transforms to faceted crystals, were only located on the edges of nacreous tablets. The tower-like deposit observed after 24 h was consisted of only aragonite crystals layered along the direction of the c-axis of nacreous tablets. |
