Lead(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula Pb O. It occurs in two polymorphs : litharge having a tetragonal crystal structure , and massicot having an orthorhombic crystal structure .
Lead sesquioxide, Pb 2 O 3, which is a lead (II,IV) oxide as well (lead(II) metaplumbate(IV) [Pb 2+][PbO 2− 3]), reddish yellow Pb 12 O 19 , 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 .
Tarnished lead (left) and shiny lead (right) Compounds of lead exist with lead in two main oxidation states: +2 and +4. The former is more common. Inorganic lead(IV) compounds are typically strong oxidants or exist only in highly acidic solutions. [1] Red α-PbO and yellow β-PbO The mixed valence oxide Pb 3 O 4 Black PbO 2 which is a strong ...
Lead(II,IV) oxide, also called red lead or minium, is the inorganic compound with the formula Pb 3 O 4. A bright red or orange solid, it is used as pigment , in the manufacture of batteries , and rustproof primer paints .
The lead monoxide is thereby reduced to metallic lead, in the midst of a slag rich in lead monoxide. [201] If the input is rich in lead, as much as 80% of the original lead can be obtained as bullion; the remaining 20% forms a slag rich in lead monoxide. For a low-grade feed, all of the lead can be oxidized to a high-lead slag. [201]

In bygone centuries it was mined. Nowadays massicot arises during industrial processing of lead and lead oxides, [6] especially in the glass industry, which is the biggest user of PbO. The definition of massicot as orthorhombic PbO dates from the 1840s, [5] but the substance massicot and the name massicot has been in use since the late medieval ...
