Lead(II) phosphate is an ionic compound with chemical formula Pb<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub>. Lead(II) phosphate is a long-lived electronically neutral reagent chemical. Despite limited tests on humans, it has been identified as a carcinogen based on tests on animals conducted by the EPA. Lead(II) phosphate appears as hexagonal, colorless crystals or as a white powder. Lead(II) phosphate is insoluble in water and alcohol but soluble in nitric acid (HNO<sub>3</sub>) and fused alkali metal hydroxides. When lead(II) phosphate is heated for decomposition it emits very toxic fumes containing Lead (Pb) and PO<sub>x</sub>.
It is prepared by reacting lead(II) hydroxide with orthophosphoric acid.
