Chemical Properties

Description
Lead phosphate is white powder soluble in acids and alkalis. Lead (II) phosphate is insoluble in water and alcohol but soluble in nitric acid and has fixed alkali hydroxides. On heating, it decomposes and emits very toxic fumes containing Pb and POx. Reports have indicated that on the basis of sufficient evidence of carcinogenicity in experimental animals and inadequate evidence for the carcinogenicity in humans, lead acetate and lead phosphate are reasonably anticipated to be human carcinogens. Information on the toxicology profile of lead phosphate is limited.
Appearance Lead phosphate is a white powder or colorless crystals.
