How is quartz glass formed and what is it used for

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

        Quartz glass uses high-purity silica sand as the raw material, and the traditional method of production is the melting-quenching method (heating the material to the melting temperature, and then rapidly cooling to the solid phase of the glass); making transparent glass with ultra-high purity and ultraviolet transmittance requires silicon The process of vaporization, oxidation into silica and heating to dissolve.

        The formation of quartz glass is the result of its high melt viscosity at high temperature. It is used in the manufacture of semiconductors, electric light sources, semiconductor communication devices, lasers, optical instruments, laboratory instruments, electrical equipment, medical equipment and high temperature and corrosion resistant chemical instruments, chemical industry, electronics, metallurgy, building materials and national defense industries. very broad.
