Lead shot glass is used in the manufacture of optical glass, electric vacuum glass, low temperature sealing glass, radiation protection glass, lead crystal glass, flint optical glass, low melting glass, delay line glass, high refraction bead glass and artware glass, etc. .

Except for glass forming materials such as silicon dioxide and boron trioxide, etc. Glass containing a large amount of lead oxide.

The composition formula of 　　 anti-radiation lead glass is: RmOn-PbO-SiO2 (B2O3). In the formula, SiO2 (B2O3), namely silicon oxide (boron oxide), is called the network formation, and it is the basic unit that constitutes the glass network structure. RmOn, a metal oxide representing alkali, alkaline earth, and rare earth metals, is a network modifier that changes the glass network structure and achieves adjustment characteristics. PbO, or lead oxide, is a characteristic component that gives the glass the basic characteristics. With the increase of PbO content, the glass's density, refractive index, dispersion, dielectric constant, X-ray and γ-ray absorption coefficient and other performance index values ​​increase; its hardness, high temperature viscosity, softening temperature, chemical stability and other index values ​​decrease; As a result, the glass molding material becomes longer, the colorant is brightly colored, the surface gloss increases, and the knocking sound is crisp.

Radiation-proof lead glass can be used for comprehensive protection in any medical, technical and research fields.

High transparency

The anti-radiation lead glass is a kind of beautiful and generous dark brown transparent board. Large transparent shielding panels that lead glass cannot reach can be made.

Toughness and durability

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

Easy to handle.

Radiation-proof lead glass can be processed by cutting, cutting, grinding, stamping, bonding and lamination. .

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