<h3>What is hydroxyapatite ?</h3>
Calcium apatite has the chemical formula Ca5(PO4)3(OH), however it is most commonly written Ca10(PO4)6(OH)2 to indicate that the crystal unit cell consists of two entities. Hydroxyapatite, also known as hydroxylapatite (HA), is a naturally occurring mineral form of calcium apatite. The complex apatite group's hydroxyl endmember is called hydroxyapatite. Fluorapatite or chlorapatite can be created by substituting fluoride, chloride, or carbonate for the OH ion. It forms a hexagonal crystal structure when it crystallizes.
Human bone contains up to 50% by volume and 70% by weight of bone mineral, a modified form of hydroxyapatite.
