The superior performance of quartz glass determines its use

       Quartz glass is made by melting various pure natural quartz (such as crystal, quartz sand, etc.). The linear expansion coefficient is extremely small, which is 1/10-1/20 of ordinary glass, and has good thermal shock resistance. Its heat resistance is very high, the temperature for regular use is 1100~1200 degrees Celsius, and the temperature for short-term use can reach 1400 degrees Celsius. Quartz glass is mainly used in laboratory equipment and refining equipment for special high-purity products.

       Quartz glass is an amorphous material with a single component of silicon dioxide. Its microstructure is a simple network composed of silicon dioxide tetrahedral structural units. Due to the large chemical bond energy of Si-O and the tight structure, quartz glass It has the properties of DuTe, especially the optical properties of transparent quartz glass are very excellent, and it has excellent transmittance in the continuous wavelength range of ultraviolet to infrared radiation.

        Quartz glass can transmit far-ultraviolet spectrum, which is the best of all ultraviolet-transmitting materials, and can transmit visible light and near-infrared spectrum. Users can choose any desired varieties from the 185-3500mμ band range according to their needs. Because quartz glass has high temperature resistance, extremely small thermal expansion coefficient and good chemical thermal stability, it is an indispensable optical material for optical systems with high stability in various harsh occasions.

        Purity is an important indicator of quartz glass, which has a great impact on physical and chemical properties and performance, such as devitrification, high temperature strength, softening point, light conduction, thermal stability, chemical stability, radiation resistance, and fluorescence properties. With the development of semiconductor technology, quartz glass is widely used in various processes of semiconductor production. Quartz glass used in the semiconductor industry has more stringent requirements for purity, and trace impurities will seriously affect the electrical properties, life and integration of semiconductor materials.

         Because quartz glass has extremely low thermal expansion coefficient, high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, ideal UV-transmitting spectral performance and visible light and near-infrared spectrum transmission performance, and has higher mechanical properties than ordinary glass. Therefore, it is a modern cutting-edge technology
