text: Amorphous calcium carbonate (ACC) is identified as a postnucleation-stage precursor phase in calcium carbonate mineralization (4, 5), in bio- (6) and biomimetic mineralization (7), and liquid precursors have been identified in some cases (8).
text: Calcite formation can proceed by several pathways, from the classical terrace ledge kink model to the crystallization of poorly ordered precursor phases (amorphous calcium carbonate, ACC) via an Ostwald ripening process, or via the agglomeration of nanocrystals.
