Introduction :Dicalcium phosphate (DCP)
Dicalcium phosphate, also known as dibasic calcium phosphate or calcium monohydrogen phosphate, is a type of calcium phosphate that is dibasic. It is usually found as the dihydrate, with the chemical formula of CaHPO4•2H2O, but it can be thermally converted to the anhydrous form, which has been referred to by the abbreviation 'DPCA'. It is practically insoluble in water, with a solubility of 0.02 g per 100 mL at 25 °C. It contains about 29.5 percent calcium in its anhydrous form. On contact with water, it converts to hydroxyapatite, which is insoluble solid, and phosphoric acid.
