Apatite - Ca 5 (PO 4) 2 [F, OH, Cl] Apatite structure is characterized by phosphate oxyanion linked by Ca 2+ cations to forma hexagonal frame-work with F-anions lying at the corners of hexagonal cell and coordinated by three Ca 2-cations. Composition of the apatite minerals is highly variable and there is a complete solid solution between three end-members, fluoroapatite Ca 5 (PO 4) 3 F

The chemical formula for this mineral family looks complicated: Ca 5 (PO 4) 3 (F,Cl,OH). Apatite is a generic name, first introduced in the mineralogical literature by Werner (1786), and used to describe calcium phosphates with simplified formula Ca 5 (PO 4) 3 X (X = F, Cl, OH). The name originates from the Greek απατάω, which means “to deceive”, because the mineral was often mistaken for other species (Fig. 1 1).Since 1856–1860, these minerals have been named Apatite is generally a group of phosphate minerals consisting of high concentration of OH−, F − and Cl − referred to as hydroxylapatite, fluorapatite and chlorapatite respectively.
