Lead(II) phosphate is an ionic compound with chemical formula Pb₃(P O₄)₂. Lead(II) phosphate is a long-lived electronically neutral reagent chemical.^[2] Despite limited tests on humans, it has been identified as a carcinogen based on tests on animals conducted by the EPA.^[3] 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 (HNO₃) and fused alkali metal hydroxides. When lead(II) phosphate is heated for decomposition it emits very toxic fumes containing Lead (Pb) and PO_x.^[4]
