(2) Widely used in the nuclear industry and aerospace field, rockets, spaceships, observation windows and insulation shell is made of quartz glass.
(3) Because of the chemical stability of quartz glass at high temperatures, which is incomparable to other engineering materials, it is widely used in chemical and pharmaceutical industries.
(4) Because of its high temperature resistance and high transmittance, quartz glass is widely used in high-tech fields such as national defense and military industries as well as new electric light sources.
(5) Because of the excellent spectral properties of quartz glass, not only through the visible light, but also through the infrared, ultraviolet, and therefore is widely used in microelectronics, information, lasers, and astronomy, optical fiber is made of quartz glass.
(6)Because of the continuous melting process for the manufacture of small diameter transparent or opaque quartz glass tubes at low cost, but without losing the characteristics of high temperature resistance, so it is used in a large number of quartz glass quality requirements are not too high for the electric light industry and far-infrared heaters.
(7) Because of the high purity of quartz glass, high temperature resistance, low thermal expansion and other excellent properties and is used in large quantities in the production of the electronics industry, such as in the doping of monocrystalline silicon wafers, diffusion, oxidation, annealing, and other key processes used in the quartz glass diffusion tubes; wafer epitaxial process used in the quartz bellows; wafer pickling and ultrasonic cleaning process used in the planter basket, bracket; wafer diffusion process using the wafer carriers (wafer carriers). Silicon wafer carrier (quartz glass boat); pulling single crystal silicon process used in the quartz crucible are made of quartz glass.
(8) in order to prevent contamination, improve product purity, in the production of polysilicon distillation tower, volatilizer (bubbler) and the feed pipe are mostly made of quartz glass.
