Calcium, combined with phosphate to form hydroxylapatite, is the mineral portion of human and animal bones and teeth.

* Calcium phosphate ( Ca < sub > 3 </ sub >( PO < sub > 4 </ sub >)< sub > 2 </ sub >) is used as a supplement for animal feed, fertilizer, in commercial production for dough and yeast products, in the manufacture of glass, and in dental products.

* Calcium phosphate

Calcium is required to buffer the excess phosphate when it enters the cells.

Calcium phosphate is the name given to a family of minerals containing calcium ions ( Ca < sup > 2 +</ sup >) together with orthophosphates ( PO < sub > 4 </ sub >< sup > 3 -</ sup >), metaphosphates or pyrophosphates ( P < sub > 2 </ sub > O < sub > 7 </ sub >< sup > 4 -</ sup >) and occasionally hydrogen or hydroxide ions.

Calcium phosphate is the principal form of calcium found in bovine milk.

Calcium phosphate is used in baking as a raising agent, with E number E341.

* Calcium dihydrogen phosphate, E341 ( i ): Ca ( H < sub > 2 </ sub > PO < sub > 4 </ sub >)< sub > 2 </ sub >

* Calcium hydrogen phosphate, E341 ( ii ): CaHPO < sub > 4 </ sub >

* Calcium phosphate storage.

** Calcium phosphate

Calcium phosphate ( phosphate rock ) is heated to 1, 200 – 1, 500 ° C with sand, which is mostly, and coke ( impure carbon ) to produce.
