Lead oxide
Appearance
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 (reddish yellow)
- 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.
