The "di" prefix in the common name arises because the formation of the HPO42–anion involves the removal of two protons fromphosphoric acid, H3PO4. It is also known asdibasic calcium phosphateorcalcium monohydrogen phosphate. Dicalcium phosphate is used as afood additive, and it is found in sometoothpastesas apolishingagent andbiomaterial.
