Lead(II) phosphate is an ionic compound with chemical formula Pb3(PO4)2. Lead(II) Phosphate is a long lived electronically neutral reagent chemical.[1] Despite limited tests on humans, it has been identified as a carcinogen based on tests on animals conducted by the EPA.[3] Properties: Hexagonal, colorless crystal or white powder. Lead(II) Phosphate is insoluble in water and alcohol but soluble in HNO3 and has fixed alkali hydroxides. When Lead(II) Phosphate is heated for decomposition it emits very toxic fumes containing Pb and POx.[5]
It is prepared by reacting lead(II) acetate with sodium orthophosphate.
