On this Wikipedia the language links are at the top of the page across from the article title. [16] In presence of chlorine, the alkyls begin to be replaced with chlorides; the R2PbCl2 in the presence of HCl (a by-product of the previous reaction) leads to the complete mineralization to give PbCl2. The PbO can be changed from massicot to litharge or vice versa by controlled heating and cooling.

[8] The tetrafluoride, a yellow crystalline powder, is unstable. The ease of oxidation of lead is enhanced by complex formation. It is used in the lead acid battery to oxidize the lead, which generates electricity. The complexation depends on halide ion numbers, atomic number of the alkali metal, the halide of which is added, temperature and solution ionic strength. it is especially poisonous to aquatic life. [3], PbO may be prepared by heating lead metal in air at approximately 600C (1,100F). [10] The diastatide has also been prepared. Lead oxide - Wikipedia PENOX Group is able to supply all grades of lead oxide with specific characteristics to achieve modern battery requirements including Start-Stop but also for high temperature applications . Metallic lead is attacked (oxidized) only superficially by air, forming a thin layer of lead oxide that protects it from further oxidation.
