The formation of quartz glass is a result of the high viscosity of the melt. Used in the manufacture of semiconductors, electric light sources, semi-conductive communication devices, lasers, optical instruments, laboratory instruments, electrical equipment, medical equipment and chemical instruments resistant to high temperature and corrosion, chemical, electronics, metallurgy, building materials and national defense industries, applications is very extensive. High-purity quartz glass can be used to make optical fibers.With the development of semiconductor technology, quartz glass is widely used in various processes of semiconductor production. For example, the Czochralski method converts polycrystals into single crystal silicon; the cleaning bath used for cleaning; the diffusion tube used for diffusion, the grooved boat; the bell jar used for ion implantation, and the like.
