Description of Nano-Hydroxylapatite Powder
Hydroxylapatite (Ca₁₀(PO₄)₆(OH)₂) is an alkaline calcium phosphate and the principal natural mineral present in bones and teeth. The hydroxyl group (OH⁻) may be replaced by fluoride, chloride or carbonate ions, thereby forming fluorapatite or chlorapatite. In addition, calcium ions can be substituted by various metal ions in ion exchange reactions, thereby producing metal apatites (M-Apatite).
