Lead oxide may refer to:
- Lead(II) oxide
Lead oxide is the chemical compound with the formula PbO. Lead oxide occurs in two forms: red, having a tetragonal crystal structure and yellow, having an orthorhombic crystal structure...
, PbO, lithargeLitharge is one of the natural mineral forms of lead oxide, PbO. Litharge is a secondary mineral which forms from the oxidation of galena ores. It forms as coatings and encrustations with internal tetragonal crystal structure. It is dimorphous with the orthorhombic form massicot...
, massicotMassicot is one of the natural mineral forms of lead oxide, PbO. Massicot is the orthorhombic dimorph of the tetragonal form of lead oxide, litharge. It forms soft yellow to reddish-yellow, earthy, scaley masses which are very dense, with a specific gravity of 9.64.It was first described in 1841...
- Lead(II,II,IV) oxide, Pb3O4, minium
Minium is a genus of thalloid alga comprising approximately 1 species. The thalli take a crustose form....
, red lead
- Lead dioxide (lead(IV) oxide), PbO2
Less common lead oxides are:
- Lead(II,IV) oxide, Pb2O3, lead sesquioxide
A sesquioxide is an oxide containing three atoms of oxygen with two atoms of another element. For example, aluminium oxide is a 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 PbO
2) is as follows:
