Product Description
The formation of quartz glass is a result of the high viscosity of the melt. 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. widely.
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 polycrystalline silicon into single crystal silicon; cleaning tanks for cleaning; diffusion tubes and tank boats for diffusion; bell jars for ion implantation, etc.
