Lead(II) fluoride (PbF2) is a chemical compound that is an odorless white solid.

It appears as the mineral fluorocronite.[2]

Conditions/substances to avoid are: strong oxidizers.


Lead(II) fluoride is used:


Lead(II) fluoride can be prepared by several methods. It is obtained by treating lead(II) hydroxide or lead(II) carbonate with hydrofluoric acid, followed by evaporation of the solution:

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
