Knowra Lead(II) oxide Lead(II) oxide Lead(II) oxide (PbO) is an inorganic compound of lead and oxygen. It occurs chiefly as red litharge and yellow massicot, two forms with different crystal structures.
Litharge : A red or reddish-yellow crystalline form of lead(II) oxide with a tetragonal structure. This is the tetragonal form of PbO, commonly contrasted with yellow massicot.
Lead(II) hydroxide : A sparingly soluble inorganic compound of lead, oxygen, and hydrogen, Pb(OH)₂. Hydration and precipitation connect PbO with this hydroxide in aqueous chemistry.
Lead glass : Glass containing lead oxide, which raises its refractive index and density. PbO is a principal source of lead in many lead-containing glasses.
Lead sulfide : A mineral compound of lead and sulfur, chiefly occurring as galena, PbS. Roasting galena in air converts its sulfur content into sulfur dioxide and forms PbO.
Lead exposure : Contact with lead through ingestion, inhalation, or, less often, skin absorption. Handling PbO can expose workers to toxic lead dust or fumes.
Massicot : A yellow orthorhombic crystalline form of lead(II) oxide. This orthorhombic form is the structural counterpart to tetragonal litharge.
Lead(II) nitrate : A soluble ionic lead salt with formula Pb(NO₃)₂. Heating this nitrate produces lead oxides, including PbO, alongside nitrogen oxides.
Lead-acid battery : A rechargeable battery that stores energy through reversible reactions of lead, lead dioxide, and sulfuric acid. Lead oxides are used in manufacturing battery plates and active materials.
Galena : The cubic mineral form of lead sulfide and the principal ore of lead. Galena is the main ore from which industrial lead oxide can be produced.
Occupational safety and health : The prevention of work-related injuries and illnesses through hazard controls and safe practices. Industrial use of PbO requires controls that limit inhalation and workplace contamination.
