This article is licensed under the GNU Free Documentation License. It uses material from the Wikipedia article "Lead_oxide".

Lead oxide may refer to:

• Lead(II) oxide, PbO, litharge, massicot
• Lead(II,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.

The sequence of the thermal transformation between the oxides in air (starting from PbO₂) is as follows^[1]:
