Product Description

Product Description:Quartz glass is made by melting various pure natural quartz (such as crystal, quartz sand, etc.). The linear expansion coefficient is very small, 1/10~1/20 of that of ordinary glass, and it has good thermal shock resistance. Its heat resistance is very high, and its regular use temperature is 1100 ºC~1200 ºC, and its short-term use temperature can reach 1400 ºC. Quartz glass is mainly used for laboratory equipment and refining equipment for special high-purity products. Because of its high spectral transmission, it will not be damaged by radiation (other glasses will become dark after being irradiated by radiation), so it is also an ideal glass for spacecraft, wind tunnel windows and spectrophotometer optical systems.

Quartz glass is a kind of special industrial glass with single component of silica. This kind of glass has a hardness of Mohs 7, high temperature resistance, low expansion coefficient, thermal shock resistance, good chemical stability and electrical insulation, and can pass through ultraviolet and infrared rays. Except hydrofluoric acid and hot phosphoric acid, it has good acid resistance to common acids. According to transparency, it can be divided into two categories: transparent and opaque. According to the purity, it can be divided into three categories: high purity, ordinary and doped. It is made of crystal, silica and silicide by high-temperature melting or chemical vapor deposition.

Quartz glass is an amorphous material with a single component of silicon dioxide, and its microstructure is a simple network composed of silicon dioxide tetrahedral structural units. Due to the large Si-O chemical bond energy and tight structure, quartz glass has unique properties, 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 has extremely low coefficient of thermal expansion, high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, the best ultraviolet spectral performance, visible and near-infrared spectral performance, and has higher mechanical properties than ordinary glass. Therefore, it is one of the indispensable excellent materials in modern cutting-edge technologies, such as space technology, atomic energy industry, national defense equipment, automation system, semiconductor, metallurgy, chemical industry, electric light source, communication, light industry, building materials and other industries.

Quartz glass is an acid material. It is inert to any acid except hydrofluoric acid and hot phosphoric acid, and is the best acid resistant material. The corrosion degree of alkali and salt to quartz glass at room temperature is also very small, so it is not ruled out that quartz glass is used in these reagents.
