Lead(II) fluoride is the inorganic compound with the formula PbF2. It is a white solid. It exists as both an orthorhombic and cubic forms. Uses Lead(II) fluoride is used in low melting glasses, in glass coatings to reflect infrared rays, in phosphors for television-tube screens, and as a catalyst for the manufacture of picoline. The Muon g−2 experiment uses scintillators in conjunction with silicon photomultipliers. Preparation Lead(II) fluoride can be prepared by treating lead(II) hydroxide or lead(II) carbonate with hydrofluoric acid: Pb(OH)2 + 2 HF → PbF2 + 2 H2O Alternatively, it is precipitated by adding hydrofluoric acid to a lead(II) salt solution, or by adding potassium fluoride to a lead(II) nitrate solution. 2 KF + Pb(NO3)2 → PbF2 + 2 KNO3 It appears as the very rare mineral fluorocronite.
