Lead Oxide

Lead oxides are a group of inorganic compounds with formulas including lead (Pb) and oxygen (O).

Common lead oxides include:

• Lead(II) oxide, PbO, litharge, massicot
• Lead(II,IV) oxide, Pb₃O₄, minium, red lead
• Lead dioxide (lead(IV) oxide), PbO₂

Less common lead oxides are:

• Lead(II,IV) oxide, Pb₂O₃, lead sesquioxide
• Pb₁₂O₁₉ (monoclinic, dark-brown or black crystals)
• The so-called black lead oxide, which is a mixture of PbO and fine-powdered metal Pb and used in the production of lead acid batteries.
