Lead Monoxide Properties

Lead Monoxide

Molecule Structure Image



Lead monoxide is an inorganic compound. It is produced on a large scale as an intermediate in the conversion of lead ores, mainly galena into metallic lead. The consumption of lead, and hence the processing of PbO, correlates with the number of automobiles because it remains the key component of automotive lead-acid batteries. It is used extensively in manufacturing of lead glasses and ceramic glazes as well as in fine dinnerware. Other less dominating applications include the vulcanization of rubber and the production of certain pigments and paints. It is used in cathode ray tube glass to block X-ray emission, but mainly in the neck and funnel because it can cause discoloration when used in the faceplate. Strontium oxide is preferred for the faceplate. PbO is used in certain condensation reactions in organic synthesis.
