Lead(II) oxide Wikipedia

Lead(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula Pb O. PbO occurs in two polymorphs: litharge having a tetragonal crystal structure, and massicot having an orthorhombic crystal structure. Modern applications for PbO are mostly in lead-based industrial glass and industrial ceramics, including computer components. It is an amphoteric oxide

19/10/2009· Maximum bone lead levels in rats fed soluble lead oxide and lead acetate were much higher (∼200 μg/g) than those seen in rats fed the less soluble lead sulfide and lead ore (∼10 μg); kidney lead concentrations were also about 10‐fold greater in rats fed the more soluble compared to the less soluble lead compounds. However, strong correlations between dose and tissue lead concentrations
