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

Contents

It appears as the mineral fluorocronite.

Conditions/substances to avoid are: strong oxidizers.

Uses

Lead(II) fluoride is used:

  • in low melting glasses
  • in glass coatings to reflect infrared rays
  • in phosphors for television-tube screens
  • as a catalyst for the manufacture of picoline

    • Preparation

    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.

    2 KF + Pb(NO3)2 → PbF2 + 2 KNO3
