Lead(II) phosphate is an ionic compound with chemical formula Pb3(PO4)2. Lead(II) phosphate is a long-lived electronically neutral reagent chemical.{{cite web |url=http://www.chemthes.com/entity_datapage.php?id=1466|title=Lead(II) phosphate|author= |date= |publisher=The Chemical Thesaurus|accessdate=11 October 2010}} Despite limited tests on humans, it has been identified as a carcinogen based on tests on animals conducted by the EPA.Wright, John, (2003). Environmental Chemistry pg 211. New York (NY): Routledge. 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 POx.Lewis, Richard J., Lewis, Richard J. Sr., (2008). Hazardous chemicals desk reference (sixth ed.) pg 831. Hoboken (NJ): John Wiley & Sons, Inc.

Preparation

It is prepared by reacting lead(II) hydroxide with orthophosphoric acid.
