Fluorapatite, often with the alternate spelling of fluoroapatite, is a phosphate mineral with the formula Ca5(PO4)3F (calcium fluorophosphate). Fluorapatite...

Apatite is a group of phosphate minerals, usually hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of OH−, F− and Cl− ion, respectively...

"phosphate rock" with acids ("acidulation"). Using phosphoric acid, fluorapatite is converted to Ca(H2PO4)2: Ca5(PO4)3F + 7 H3PO4 → 5 Ca(H2PO4)2 + HF...
