Calcium Phosphate

Calcium phosphate is the name given to a family of minerals containing calcium ions (Ca2+) together with orthophosphates (PO₄3-), metaphosphates or pyrophosphates (P₂O₇4-) and occasionally hydrogen or hydroxide ions.

Calcium phosphate is the principal form of calcium found in bovine milk. Seventy percent of bone consists of hydroxyapatite, a calcium phosphate mineral (known as bone mineral). Tooth enamel is composed of almost ninety percent hydroxyapatite.
