Description of Dicalcium phosphate
Monetite is the calcium phosphate with the formula CaHPO4. 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. There are three crystalline forms: a dihydrate, CaHPO4•2H2O (‘DPCD’), the mineral brushite; a hemihydrate, CaHPO4•0.5H2O; and anhydrous CaHPO4, (‘DCPA’), the mineral monetite. Below pH 4.8 the dihydrate and anhydrous forms of dicalcium phosphate are the most stable (insoluble) of the calcium phosphates. Dicalcium phosphate is used as a food additive, it is found in some toothpastes as a polishing agent and is a biomaterial. In the dihydrate (brushite) form it is found in some kidney stones and in dental calculi

What is Dicalcium phosphate?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives.
- One such product is Monetite which has developed particularly rapidly in recent years. Do you know about Monetite?
- The official answer:Monetite is an inorganic substance with the chemical formula CaHPO4, a white monoclinic crystalline powder, odourless and tasteless, soluble in dilute hydrochloric acid, dilute nitric acid, acetic acid, slightly soluble in water (100°C, 0.025%), insoluble in ethanol, usually in the form of dihydrate (CaHPO4-2H2O).
- The dihydrate is stable in air and starts to lose its water of crystallisation when heated to 75°C and becomes anhydrous, at high temperature it becomes pyrophosphate.
What’s the application of Dicalcium phosphate?
As a food feed additive to supplement the phosphorus and calcium elements in livestock feed.
