This is particularly true for dicalcium phosphate (DCP), a food additive produced from either sulphuric acid or hydrochloric acid digestion of raw rock material. This study determined the natural occurring radionuclide concentrations of 12 DCP samples and 4 tricalcium phosphate (TCP) samples used for animal and human consumption, respectively.
Calcium and phosphorus make up the majority of an animals mineral nutrient requirements (to fulfill both body tissue and milk needs), therefore DCPD is a common and widely used animal supplement. Dicalcium Phosphate Dihydrate is also of interest because it is the most soluble of the sparingly soluble calcium phosphate minerals and thus makes a ...

Monocalcium phosphate is an inorganic compound with the chemical formula Ca(H 2 PO 4) 2 ("AMCP" or "CMP-A" for anhydrous monocalcium phosphate). It is commonly found as the monohydrate ("MCP" or "MCP-M"), Ca(H 2 PO 4) 2 ·H 2 O. Both salts are colourless solids. They are used mainly as superphosphate fertilizers and are also popular leavening agents.
