Dicalcium Phosphate

Dicalcium Phosphate (a.k.a. DCP), also known as dibasic calcium phosphate or calcium monohydrate phosphate, is a type of calcium phosphate that is practically insoluble in water. With a solubility of 0.02 g per 100 mL at 25 °C, on contact with water, it converts to hydroxyapatite, which is insoluble solid, and phosphoric acid.

It is a calcium and phosphorus feed supplement for animals (cattle, poultry, beef, and sheep), containing 18% of phosphate and calcium.
