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[]

Two 25 mm × 25 mm × 140 mm PbF
₂ scintillator crystals used in the Muon g−2 experiment.

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.^[2] The Muon g−2 experiment uses PbF
₂ scintillators in conjunction with silicon photomultipliers.^[3]

Preparation[]

Lead(II) fluoride can be prepared by treating lead(II) hydroxide or lead(II) carbonate with hydrofluoric acid:^[2]

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.^[4]

2 KF + Pb(NO₃)₂ → PbF₂ + 2 KNO₃

It appears as the very rare mineral .^[5]^[6]
