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:
