Effect of Annealing on Calcium Carbonate Morphology of Mollusk Shell
After the aragonite nacreous layer and cross section of Periglypta Magnifica mollusk shell were annealed, the influences, including crystallization temperatures, crystallization time and concentrations of calcium chloride aqueous solution on the crystal morphology of annealed shell was studied. These three factors evidently influenced the crystal morphology of calcium carbonate, whose annealed morphology was different from its origin. In addition, the cross section of annealed shell contained three crystallized regions of calcium carbonate.
