Industrial Uses

1. Metal Treatment

  • Refining Lead Alloys: Lead fluoride is used in a flux to remove impurities like zinc and tin from lead alloys. This process involves adding PbF2 to molten lead alloys, which facilitates the oxidation of the impurities (zinc or tin), allowing them to be removed from the alloy.
  • Controlling Perovskite Crystal Growth: In the development of perovskite solar cells, PbF2 acts as an additive to control the growth of perovskite crystals. The fluoride ions (F-) from PbF2 can effectively passivate the surface of perovskite grains, leading to improved optical and electrical characteristics and higher power conversion efficiency.

2. Performance Chemicals

  • Precursor: Lead fluoride (PbF₂) is used as a precursor in various chemical syntheses, particularly for preparing other lead-containing compounds.
