Phosphate Minerals in Human Tissues SpringerLink
Abstract. The mineralized or calcified tissues in biological systems are composed of two phases: organic and inorganic or mineral phases. In the invertebrates (e.g., echinoderms, mollusks, arthropods, etc.), the inorganic phase is usually calcium carbonate, CaCO 3, predominantly in the form of either calcite or aragonite or both.

Hydroxyapatite: Mechanism of formation and properties
Hydroxyapatite (HA) was prepared by stirring amorphous calcium phosphate (ACP), which contained occluded Cl− as a tracer ion, in distilled water buffered to pH 7.4 by tris-HCl at 25, 37, 60, 80 and 100°. HA made in this manner contained from less than 1% (25°) to 11% (100°) of the amount originally occluded in the precursor ACP. These results suggest that
