Crystallization of calcium carbonate, typically, progresses sequentially via metastabIc phases. Amorphous CaC03 (ACC) generally forms initially, both in vitro and in vivo, and is the precursor of the predominant anhydrous polymorphs (calcite, aragonite, and vaterite). [I-I3] A new picture of the crystallization of calcium carbonate is emerging, which involves transformations of clusters to ACC and eventually to crystalline polymorphs,P4.15] This stepwise manner has implications for the… CONTINUE READING
