'''Lead(II) oxide''', also called '''lead monoxide''', is the [[inorganic compound]] with the molecular formula [[lead|Pb]][[oxide|O]]. It occurs in two [[Polymorphism (materials science)|polymorph]]s: [[litharge]] having a [[tetragonal crystal system|tetragonal crystal structure]], and [[massicot]] having an [[orthorhombic crystal system|orthorhombic crystal structure]]. Modern applications for PbO are mostly in [[lead]]-based industrial [[lead glass|glass]] and industrial ceramics, including computer components.
