What is apatite crystal form?
Apatite has the composition Ca5[PO4]3(OH,F,Cl) and is the major primary mineral source of phosphorous to most soils. It has a hexagonal crystal system and variable composition. Fluorine, hydroxyls, chlorine, and others may substitute in the structure freely, thus forming fluorapatite, hydroxyapatite, chlorapatite, etc.
What type of minerals is apatite?
Apatite is a phosphate mineral (and is the most abundant phosphorous-bearing mineral). The name actually covers three different minerals (fluorapatite, chlorapatite and hydroxylapatite) depending on the predominance of either fluorine, chlorine or the hydroxyl group.
