Cadmium phosphate is an inorganic phosphate salt of cadmium, with the molecular formula Cd3(PO4)2.[2] It is a white, water-insoluble solid.
Synthesis
Tricadmium phosphate can be prepared by the reaction of cadmium chloride with diammonium phosphate at 800 °C:[3]
- 3 CdCl2 + 2 (NH4)2HPO4 → Cd3(PO4)2 + 4 NH4Cl + 2 HCl
The precipitation of aqueous cadmium ions with soluble phosphate sources, such as trisodium phosphate and phosphoric acid, does not produce Cd3(PO4)2, but instead produces a hydrate of cadmium with the formula Cd5H2(PO4)4·4H2O. When this compound is heated, it yields a mixture of cadmium phosphate and cadmium pyrophosphate, Cd2P2O7.[4]
Uses
Cadmium phosphate can be used as a fertilizer to provide phosphorus to crops for their growth.[2]
