Fluorapatite, often with the alternate spelling of fluoroapatite, is a phosphate mineral with the formula Ca5(PO4)3F (calcium fluorophosphate). ... It is often combined as a solid solution with hydroxylapatite (Ca5(PO4)3OH or Ca10(PO4)6(OH)2) in biological matrices. Chlorapatite (Ca5(PO4)3Cl) is another related structure.
What type of mineral is fluorapatite?
fluorapatite, common phosphate mineral, a calcium fluoride phosphate, Ca5(PO4)3F. It occurs as minute, often green, glassy crystals in many igneous rocks, and also in magnetite deposits, high-temperature hydrothermal veins, and metamorphic rocks; it also occurs as collophane in marine deposits.
Where does hydroxyapatite come from?
Hydroxyapatite is a naturally occurring mineral of biological and agricultural importance. Human and animal bones are composed of hydroxyapatite. In nutrient recovery processes, hydroxyapatite is generated through treatment of waste streams containing calcium.
