What are the characteristics of quartz glass?

        Quartz glass has extremely low thermal expansion coefficient, high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, relatively good ultraviolet and extra-spectral performance, and visible light and near-infrared transmission. Spectral properties, and have higher mechanical properties than ordinary glass. Therefore, it is one of the indispensable excellent materials in space technology, atomic energy industry, national defense equipment, automation system, and semiconductor, metallurgy, chemical industry, point light source, communication, light industry, building materials and other industries in modern cutting-edge technology.
