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. 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.
- CaCO3 + H3PO4 → CaHPO4 + H2O + CO2
Dicalcium phosphate is mainly used as a dietary supplement in prepared breakfast cereals, dog treats, enriched flour, and noodle products. It is also used as a tableting agent in some pharmaceutical preparations, including some products meant to eliminate body odor. It is used in poultry feed. It is also used in some toothpastes as a tartar control agent.
