Rock phosphate is the source from which dicalcium phosphate can be manufactured. It finds applicability as a fertilizer and animal feed. The phosphours pentoxide content ranges around 41-42 in the dihydrate form. The trade mark for a dentrifice grade dicalcium phosphate dihydrate is captioned as Dicalcium phosphate victor .

Dicalcium phosphate crystals are precipitated and after filtration and drying the resulting product is a very pure crystalline dihydrate dicalcium phosphate that is sold as Aliphos Dical. Dicalcium phosphate is obtained from degreased bones which are demineralised by hydrochloric acid treatment and precipitated by a saturated lime solution.
Dicalcium phosphate is difficult to make in high purity under any conditions and this particular phosphate will usually be made in a mixture with monocalcium phosphate andor calcium chlorophosphate. It is preferable to leave some chloride in the product mixture to avoid the use of the high drying temperatures required to remove chloride.

Paul Scott Dicalcium phosphate powder. Dicalcium phosphate DCP is a dibasic calcium phosphate formed by a reactive combination of calcium oxide and phosphoric acid. As a dietary supplement, it is commonly used as a source of calcium and phosphorus for both humans and animals. In this role, the compound is either used as an additive in the preparation of cereal and grain products or purchased ...
