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.


Lead(II) fluoride is used:[2]


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.[3]

2 KF + Pb(NO3)2 → PbF2 + 2 KNO3

It appears as the rare mineral fluorocronite.[4]
