Hydroxyapatite Powder Description
Hydroxyapatite, also known as hydroxyapatite (HA), alkaline calcium phosphate, is mineralized natural apatite (Ca5(PO4)(OH)). The OH-base can be fluorine, chlorine, and carbonate ions to generate fluoroapatite or chlorinated matrix apatite. The calcium ions of HA can be combined with various metal ions through ion exchange reaction to form corresponding metal ions.
