Lead shot glass is used in the manufacture of optical glass, electric vacuum glass, low-temperature sealing glass, radiation-proof glass, lead crystal glass, flint optical glass, low melting point glass, delay line glass, high refractive bead glass and handicraft glass.

In addition to glass forming materials, such as silicon dioxide and boron trioxide. Glass containing a large amount of lead oxide.

The composition of radiation-proof lead glass is: RmOn-PbO-SiO2 (B2O3). In the formula, SiO2 (B2O3), I .e., silicon oxide (boron oxide), is referred to as network formation, which is a basic unit constituting a glass network structure. RmOn, a metal oxide representing an alkali metal, an alkaline earth metal, and a rare earth metal, is a network modifier that changes the glass network structure and achieves adjustment characteristics. PbO or lead oxide is a characteristic component that imparts basic characteristics to the glass. With the increase of PbO content, the density, refractive index, dispersion, dielectric constant, X-ray and γ-ray absorption coefficient and other performance index values of the glass increase; its hardness, high temperature viscosity, softening temperature, chemical stability and other index values Decrease; as a result, the glass forming material becomes longer, the color of the colorant is bright, the surface gloss increases, and the knocking sound is clear.

Anti-radiation lead glass can be used for comprehensive protection in any medical, technical and research field.

High transparency

Anti-radiation lead glass is a beautiful dark brown transparent plate. Can make lead glass can not reach large transparent shielding panel.

toughness and durability

The mechanical and thermal properties of the anti-radiation lead glass are basically the same as those of the acrylic resin.. The impact resistance is also very superior.

Easy to handle.

The radiation-proof lead glass can be processed by cutting, grinding, stamping, bonding and laminating..

Also. The concept and application of anti-radiation coating (barium sulfate) also reflects the advantages of lead glass.
