Lead oxide
Encyclopedia
Lead oxide may refer to:
Less common lead oxides are:
- Lead(II) oxideLead(II) oxideLead oxide is the inorganic compound with the formula PbO. Lead oxide occurs in two polymorphs, red, having a tetragonal crystal structure and yellow, having an orthorhombic crystal structure...
, PbO, lithargeLithargeLitharge 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...
, massicotMassicotMassicot 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, red lead
- Lead dioxide (lead(IV) oxide), PbO2
Less common lead oxides are:
- Lead(II,IV) oxide, Pb2O3, lead sesquioxideSesquioxideA 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., Al2O3, La2O3...
- 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.
