Description and Uses
Lead fluoride is a white to colorless, odorlesscrystalline (rhombic, orthorhombic) solid. Molecularweight =245.19; Boiling point=1292℃; Freezing/Meltingpoint = 825℃. Hazard Identification (based on NFPA-704M Rating System): Health 1, Flammability 0, Reactivity 0.Slightly soluble in water.
Lead(II) fluoride is used in fuses, glass coatings to reflect infrared rays and phosphors for television screens and in low melting glasses. Further, it serves as a catalyst for the preparation of picoline.
