Calcium orthophosphates (Calcium phosphates, calcium phosphate, monocalcium phosphate, dicalcium phosphate, tricalcium phosphate, calcium orthophosphate, single-substituted calcium orthophosphate, double-substituted calcium orthophosphate, tri-substituted calcium orthophosphate, calcium tripolyphosphate, calcium phosphate, E341) are calcium salts of orthophosphoric acid.
Types of calcium orthophosphates (calcium phosphates):
- (i) Single-substituted calcium orthophosphate (monocalcium phosphate, Ca[H2PO4]2);
- (ii) Calcium orthophosphate, disubstituted (dicalcium phosphate, CaHPO4);
- (iii) Tri-substituted calcium orthophosphate (tricalcium phosphate, Ca3O8P2).
