ACP has been shown to rapidly hydrolyze to form apatite, similar to carbonated apatite, the tooth mineral. Apatite mineral uses also extend to fluoridating water, and a protective coat of apatite on metals prevent it from rusting. The common mineral apatite has formula Ca5(PO4)3X, where X is F, Cl, OH, or a mixture; it is hydroxyapatite if the extra ion is mainly hydroxide. Apatite is the defining mineral for 5 on the Mohs scale. Apatite now and then is found to contain large amounts of rare-earth elements and can be used as an ore for some metals. Both iron oxide-apatite (IOA) and iron skarn deposits are closely associated with intrusive rocks of intermediate to felsic in composition, but whether these two ore types can form from the same magmatic intrusion remains poorly understood. ... apatite.
