Tricalcium phosphate (sometimes abbreviated TCP) is a calcium salt of phosphoric acid with the chemical formula Ca 3 (PO 4) 2.It is also known as tribasic calcium phosphate and bone phosphate of lime (BPL).It is a white solid of low solubility. Most commercial samples of "tricalcium phosphate" are in fact hydroxyapatite.. It exists as three crystalline polymorphs α, α', and β.

Dicalcium phosphate is the calcium phosphate with the formula CaHPO4 and its dihydrate. 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.

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.

The successive production steps which can reduce the potential infectivity of the raw material are thus, apart from the degreasing and demineralisation steps, different for gelatine and dicalcium phosphate. On the safety of dicalcium phosphate precipitated from bones in particular, or on by-

Mar 04, 2018· The IUPAC name of this compound is Calcium hydrogen phosphate dehydrate. The reactants used for the production of Dicalcium phosphate include calcium hydroxide (Ca(OH) 2) and phosphoric acid (H 3 PO 4). The production process include the neutralization of calcium hydroxide by phosphoric acid that gives Dicalcium phosphate as a dehydrate ...

Oct 26, 1976· The invention relates to a combined process for the manufacture of feed grade dicalcium phosphate and pure phosphoric acid. 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 ...

Abstract. This paper presents results laboratory experiments to test a new process for manufacture of dicalcium phosphate. The process is based on the nitric acidulation of phosphate rock concentrate, followed by neutralization of the extract liquor with calcium carbonate.

The production process for toothpaste A typical toothpaste process starts with a very viscous dicalcium phosphate slurry, which is the abrasive component. The slurry is blended with gum solution to form a white cream base or common base (CB) and small amounts of post-addition (PA) ingredients must be dispersed to make the final products.

Oct 13, 2018· Dicalcium phosphate is a calcium supplement generally found in pharmaceuticals as an inert ingredient to bind tablets, in prepared breakfast cereals, and in toothpaste. It is also known as E341. Chemical Formula. HCaO4P. Vegan. Phosphate is a mineral commonly derived from rocks, however, occasionally from bones and whey (from cheese-making).
