CALCIUM PHOSPHATE, DIBASIC Usage And Synthesis
Uses Dibasic calcium phosphate is found in nature as the mineral monetite. It is used as a food supplement and source of calcium, both in human food and animal feed. It is used in dough conditioner; in several dental products and in medicine. Other applications are in fertilizers, plastics and in the manufacture of glass.
Preparation Dibasic calcium hydrogen phosphate may be prepared by several methods.
It is precipitated by mixing solutions of calcium chloride and disodium hydrogen phospate: CaCl2 + Na2HPO4 → CaHPO4 + 2NaCl
It also is prepared by treating phosphoric acid with lime water (suspension of calcium hydroxide in water). Also, it is obtained as a by-product in the preparation of hydroxypatite. The preparation involves the reaction of phosphoric acid with calcium phosphate.
H3PO4 + Ca3(PO4)2 → 3CaHPO4
