Calcium Nutrition of Broilers: Current Perspectives and …
Dicalcium phosphate is produced by the neutralisation of Ca hydroxide with phosphoric acid, which precipitates the dihydrate as a solid or by reacting phosphoric acid with limestone. The purity of the DCP depends on the origin of the raw material and procedures employed in its industrial production.

Understanding phosphorus fertilizers | UMN Extension
The phosphoric acid produced by either the wet or dry process is frequently heated, driving off water and producing a superphosphoric acid. The phosphate concentration in superphosphoric acid usually varies from 72 to 76 percent. The P in this acid is present as both orthophosphate and polyphosphate. Polyphosphates consist of a series of ...
