Lead oxide

From Wikipedia, the free encyclopedia

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 tetroxide or red lead , Pb 3 O 4 , minium , which is a lead (II,IV) oxide and may be thought of as lead(II) orthoplumbate(IV) [Pb 2+ ] 2 [PbO 4? 4 ] , vivid orange crystals
  • Lead dioxide (lead(IV) oxide), PbO 2 , dark-brown or black powder

Less common lead oxides are:

  • 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 .
