Kalziumphosphate
Kalziumphosphate, or calcium phosphate, denotes a family of inorganic compounds composed of calcium and phosphate ions. The term covers several stoichiometries and hydration states, including monocalcium phosphate Ca(H2PO4)2, dicalcium phosphate CaHPO4, and tricalcium phosphate Ca3(PO4)2, as well as phosphate-containing minerals such as hydroxyapatite Ca10(PO4)6(OH)2 and related apatites.
Common solid forms include monocalcium phosphate monohydrate Ca(H2PO4)2·H2O, dicalcium phosphate dihydrate CaHPO4·2H2O (brushite), and anhydrous Ca3(PO4)2.
Occurrence and roles: In biology, calcium phosphate provides rigidity to bone and teeth and participates in
Uses: In agriculture, calcium phosphates supply phosphorus and calcium to crops. In the food industry, they
Safety: Calcium phosphates are generally of low toxicity, but dust can irritate the eyes and respiratory tract;
