· In general, calcium carbonates exist either in the form of amorphous calcium carbonate (ACC) or one of the three polymorphs, namely, calcite, aragonite, and vaterite (Figure 1). Two hydrated phases of calcium carbonate, monohydrate (CaCO 3 ⋅H 2 O), and hexahydrate of calcium carbonates (CaCO 3 ⋅6H 2 O) are also possible forms of hydrated calcium carbonates.
