Dicalcium phosphate is the calci um phosphate with the formula CaHPO 4 and its dihydrate. The "di" prefix in the common name arises because the formation of the HPO 4 2– anion involves the removal of two protons from phosp horic acid, H 3 PO 4. It is also known as dibasic calcium phosphate or calcium monohydrogen phosphate.
Apr 01, 1994· A new process for the production of defluorinated dicalcium phosphate using phosphate rock was developed. This new process has the main characteristic of being clean, without the production of any liquid waste. The process has essentially three main steps: phosphate rock digestion, defluorination and neutralization.

Aug 07, 2020· Monocalcium phosphate is a powder of medium hygroscopicity (granules 0.2-1.4 mm in size) - white or grey colour, and easily soluble in a water environment. Compared with other inorganic sources of phosphorus, such as dicalcium phosphate and tricalcium phosphate, MCP has the following features and advantages:
The dicalcium phosphate forms a protective coating to the underlying hydroxyapatite since is is removed relatively slowly, the rate depending on the concentration of calcium and phosphate ions to which it is exposed at the tooth surface. The process is shown in Figure 35.7 (period A) in which calcium phosphate solubility is related to pH.

Dicalcium phosphate is a crystalline feed grade Dicalcium phosphate containing 19.0% Minimum phosphorous and 28.0% Maximum calcium. The selected raw material of non-animal origin and the production process ensures an end product with good phosphorous digestibility and a content of undesirable elements well below that stipulated by EU feed legislation.
70 and 80°C on dicalcium phosphate are brought in Figures 2, 3, 4 and 5. According to their shape, these isotherms are Type II on BET classification indicating that dicalcium phosphate is macro-porous (pore diameter>200 A°).
