General description

Lead(II) oxide (PbO) is an industrially important metal oxide with strong absorption cross sections, high carrier mobilities, and conductivities. It is widely applied in the field of storage batteries, dielectrics, gas sensors, pigments, and paints.

Application

Lead(II) oxide can be used as a precursor to prepare:
  • Gamma ray radiation shielding glasses such as GeO2-PbO-Al2O3–CaO glasses.
  • Perovskite ceramic materials. For example, it can be used to synthesize lead magnesium niobate, widely applied in the field of electronic ceramics due to its high dielectric constant and voltage stability.
