Dicalcium Phosphate - an overview | ScienceDirect Topics

The abrasives used in modern day dentifrices typically include hydrated silica, calcium carbonate, dicalcium phosphate dihydrate (DCPD), calcium pyrophosphate, alumina, perlite and sodium bicarbonate [109]. They are the key ingredients for cleaning of the teeth, and they function by a process termed abrasion.


Calcium Phosphate Solubility: The Need for Re-Evaluation ...

Dec 09, 2008· Using solid titration, the true solubility isotherm of hydroxyapatite (HAp) has been found to lie substantially lower than previously reported. In addition, contrary to wide belief, dicalcium phosphate dihydrate (DCPD) is not the most stable phase below pH ∼4.2, where calcium-deficient HAp is …

Dicalcium-Phosphates- Process, Technology, Applications ...

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.


Processes for the manufacture of feed-grade dicalcium ...

Oct 26, 1976· The process comprises the reaction of an excess of phosphate rock with aqueous solutions of a mineral acid selected from hydrochloric acid, phosphoric acid and nitric acid, characterized by the fact that the free acidity of the dissolution liquor does not exceed 60% and that in the clear solution feed grade dicalcium phosphate is precipitated with calcium hydroxide, calcium carbonate …

Dicalcium phosphate - Wikipedia

To prevent degradation that would form hydroxyapatite, sodium pyrophosphate or trimagnesium phosphate octahydrate are added when for example, dibasic calcium phosphate dihydrate is to be used as a polishing agent in toothpaste. In a continuous process CaCl 2 can be treated with (NH 4) 2 HPO 4 to form the dihydrate: CaCl 2 + (NH 4) 2 HPO 4 → CaHPO 4 •2H 2 O
