Depending on the glass, the benefit of using PbO in glass can be one or more of increasing the refractive index of the glass, decreasing the viscosity of the glass, increasing the electrical resistivity of the glass, and increasing the ability of the glass to absorb X-rays. Select Language. lead compounds are the oxides: lead monoxide, PbO, in which lead is in the +2 state; lead dioxide, PbO2, in which lead is in the +4 state; and trilead tetroxide, Pb3O4. Modern applications for PbO are mostly in lead-based industrial glass and industrial ceramics, including computer components. The refractive indices, dispersive powers, and electrical resistance of these glasses are generally much greater than those of soda-lime-silica, of the glass: addition of lead oxide, for example, was found to raise both the refractive index and the dispersive power.

This website provides you with a range of general information on our company, products and activities. Lead(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula PbO. At this temperature it is also the end product of decomposition of other oxides of lead in air:[4]. PbO2 exists in two crystalline forms. Therefore, an alternative method is to use harder substrates, such as titanium, niobium, tantalum or graphite and deposit PbO2 onto them from lead(II) nitrate in static or flowing nitric acid. A bright red or orange solid, it is used as pigment, in the manufacture of batteries, and rustproof primer paints. Lead Oxide. PbO - YouTube When heated with nitrates of alkali metals, metallic lead oxidizes to form PbO (also known as litharge), leaving the corresponding alkali nitrite. lead dioxide anodes were used for the production of glyoxylic acid from oxalic acid in a sulfuric acid electrolyte.
