Product Description:Quartz glass is made by melting various pure natural quartz (such as crystal, quartz sand, etc.). The thermal 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 1100ºC~1200ºC, and the temperature for short-term use can reach 1400ºC. Quartz glass is mainly used in laboratory equipment and refining equipment for special high-purity products. It is also an ideal glass for use in spacecraft, wind tunnel windows and spectrophotometer optical systems due to its high spectral transmission and is not damaged by radiation (other glasses will darken when exposed to radiation).
Quartz glass is a special industrial technical glass with a single component of silica. The hardness of this glass can be as high as Mohs 7, with high temperature resistance, low expansion coefficient, thermal shock resistance, chemical stability and good electrical insulation properties, and can transmit ultraviolet and infrared rays. Except for hydrofluoric acid and hot phosphoric acid, it has good acid resistance to general acids. According to the transparency, it is divided into two categories: transparent and opaque. According to the purity, it is divided into three categories: high-purity, ordinary and doped.
Quartz glass has a very low thermal expansion coefficient, high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, the best UV spectral performance and visible light and near-infrared spectral transmission performance, and has 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, electric light source, communication, light industry, building materials and other industries in modern cutting-edge technology.
