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 (α-PbO, tetragonal, red), massicot (β-PbO, orthorhombic, yellow) Lead tetroxide or red lead, , minium, which is a lead (II,IV) oxide and may be thought of as lead(II) orthoplumbate(IV) , vivid orange crystals Lead dioxide (lead(IV) oxide), , dark-brown or black powder, scrutinyite (α-, orthorhombic), plattnerite (β-, tetragonal)
Less common lead oxides are: Lead sesquioxide, , which is a lead (II,IV) oxide as well (lead(II) metaplumbate(IV) ), reddish yellow
, monoclinic, dark-brown or black crystals The so-called black lead oxide, which is a mixture of PbO and fine-powdered Pb metal and used in the production of lead–acid batteries.
