Dicalcium Phosphate 50 Lb Bags – FeedsForLess

Dicalcium phosphate is the calcium phosphate with the formula CaHPO4 and its dihydrate. The di prefix in the common name arises because the formation of the HPO42– anion involves the removal of two protons from phosphoric acid, H3PO4. It is also known as dibasic calcium phosphate or calcium monohydrogen phosphate. DiGet price

Nitric acid acidulation of phosphate rock and pyrolysis of

A modified method for producing a range of dicalcium phosphate containing phosphatic fertilizers and aqueous calcium nitrate is discussed. The process consists of reacting phosphate rock with nitric acid followed by pyrolysis of the resulting acidulate to produce dicalcium phosphate (CaHPO4) and to liberate approximately one-half of the initially consumed nitric acid.Get price
