Lead Glass

In addition to silica, boron trioxide formation, such as glass containing more quantity lead oxide in the glass.Used in the manufacture of optical glass, electric vacuum glass, low temperature sealing glass, anti-radiation glass, lead crystal glass, flint, delay line glass, optical glass, low melting glass high refractive beads and art ware glass, etc.

The composition of lead glass type: RmOn - PbO - SiO2 (B2O3).Type of SiO2 (B2O3), namely, silicon oxide (boron oxide), said the network formation, is the basic unit of a glass network structure.RmOn, on behalf of alkali, alkaline earth and rare earth metal oxide of metal, is to make the glass network structure change, achieve the adjustment features network changes.PbO, i.e., lead oxide, composition, characterized by glass basic characteristics.
