Lead oxide
 
  Lead oxide may refer to:

  • Lead(II) oxide
    Lead(II) oxide

    Lead oxide is the chemical compound with the chemical formula leadoxide. Lead oxide occurs in two forms: red, having a tetragonal crystal system and yellow, having an orthorhombic crystal system....
    , PbO, litharge
    Litharge

    Litharge 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 system....
    , massicot
    Massicot

    Massicot is one of the natural mineral forms of lead oxide, PbO. Massicot is the orthorhombic crystal system dimorph of the tetragonal crystal system form of lead oxide, litharge....
  • 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
    Sesquioxide

    A sesquioxide is an oxide containing three atoms of oxygen with two atoms of another element. For example, aluminium oxide is a sesquioxide.Many sesquioxides contain the metal in the +3 oxidation state and the oxide ion e.g....
  • 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:
