Lead dioxide is produced commercially by several methods, which include oxidation of red lead (Pb 3 O 4) in alkaline slurry in a chlorine atmosphere, [6] reaction of lead(II) acetate with "chloride of lime" (calcium hypochlorite), [9] [10] The reaction of Pb 3 O 4 with nitric acid also affords the dioxide: [2] [11] Pb 3 O 4 + 4 HNO 3 → PbO 2 ...
PbO is produced on a large scale as an intermediate product in refining raw lead ores into metallic lead. The usual lead ore is galena (lead(II) sulfide). At a temperature of around 1,000 °C (1,800 °F) the sulfide is converted to the oxide: [5] 2 PbS + 3 O 2 → 2 PbO + 2 SO 2
Lead oxides are a group of inorganic compounds with formulas including lead (Pb) and oxygen (O).. Common lead oxides include: Lead(II) oxide, PbO, litharge (red), massicot (yellow)
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.
Scrutinyite / ˈ s k r uː t ɪ n i. aɪ t / is a rare oxide mineral and is the alpha crystalline form of lead dioxide (α-PbO 2), plattnerite being the other, beta form. The mineral was first reported in 1988 and its name reflects the scrutiny and efforts required to identify it from a very limited amount of available sample material.
The name lead hydrate has sometimes been used in the past but it is unclear whether this refers to Pb(OH) 2 or PbO·xH 2 O. [6] [7] In 1964 it was believed that such a simple compound did not exist, as lead basic carbonate (2PbCO 3 ·Pb(OH) 2) or lead(II) oxide (PbO) was encountered where lead hydroxide was expected. [8]
Plattnerite is found in numerous arid locations in North America (US and Mexico), most of Europe, Asia (Iran and Russia), Africa and Southern and Western Australia.It occurs in weathered hydrothermal base-metal deposits as hay-like bundles of dark prismatic crystals with a length of a few millimeters; the bundles grow on, or sometimes within various minerals, [5] including cerussite ...
Plumbates are formed by the reaction of lead(IV) oxide, PbO 2, with alkali. [4] [5] Plumbate salts contain either the hydrated hexahydroxoplumbate(IV) or plumbate anion [Pb(OH) 6] 2−, or the anhydrous anions PbO 2− 3 (metaplumbate) or PbO 4− 4 (orthoplumbate). [4]
