Hydroxylapatite, also called hydroxyapatite (HA), is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4) 3 (OH), but is usually written Ca 10 (PO 4) 6 (OH) 2 to denote that the crystal unit cell comprises two entities. Hydroxylapatite is the hydroxyl endmember of the complex apatite group.
Experienced observers can sometimes recognize phlogopite by its brown color. As noted above, biotite is a name used for a number of black mica minerals that have different chemical compositions but very similar physical properties.These minerals generally can not be distinguished from one another without laboratory analysis.xperienced observers can sometimes recognize phlogopite by its brown color.
