Quartz plate is akind of special glasscontainingonly onecomponent –SiO2,our company"s production of
quartz glass is producedusing natural crystal fused process and madeafter fine polished,which is colorless
transparent, no bubbles,no pulling marks and otherprocessing traces in its appearance ,with very low
coefficient of thermalexpansion, high temperature resistance, excellent chemical stability, excellent
electrical insulation,stable ultrasound delay performance, the best transmission ultraviolet spectrum
performance and higher mechanical properties than common glass.The purity is controlled in PPM orders of
magnitude. It is one of the indispensable materials in modern advanced spacetechnology, atomic energy
industry, national defense equipment, automationsystem, and semiconductors, metallurgy, chemical industry,
electric lightsource, communication,light industryand constructionindustry.
