Quartz glass plate

Quartz is a hard, abundant mineral (SiO₂). Its piezoelectricity enables precise timing in watches and electronics, while its varieties serve as gemstones and industrial materials.

 

01 Complete size, support customization

Our professional custom processes ensure that your needs are met. Precision instrument, simple quartz tube and quartz sheet,various specifications complete,if necessary, you can contact at any time.

02 High temperature resistance 1200°, corrosion resistance

The softening point temperature of quartz glass is about 1730’℃,which can be used for a long time at 1200’and it is not easy to have chemical reaction with other substances.

03 High precision, high flatness, high finish

Factory through precision grinding, calcination, polishing, burning, in order to ensure the product finish, precision, and the entire product flatness

04 High transmittance UV>94%

Good light transmission in all wavelengths from ultraviolet to infrared.
