Dicalcium phosphate Wikipedia

Dicalcium phosphate is the calcium phosphate with the formula CaHPO 4 and its dihydrate. The "di" prefix in the common name arises because the formation of the HPO 4 2– anion involves the removal of two protons from phosphoric acid, H 3 PO 4.It is also known as dibasic calcium phosphate or calcium monohydrogen phosphate.Dicalcium phosphate is used as a food additive, it is found in some

PRODUCTION OF PHOSPHORIC ACID Product Stewardship

Processes with different raw materials are used in the manufacture of phosphoric acid. The process is known as “thermal” when the raw material is elemental phosphorus. This process has been abandoned because of the amount of energy which is needed. The processes that use phosphated minerals which are decomposed with an acid, are known as “wet processes” and they are the only
