Formation and use of quartz tubes
The formation of quartz glass is the result of its high viscosity at high temperature. Used in the production of semiconductors, electro-optical sources, semi-conductive communication devices, lasers, optical instruments, laboratory instruments, electrical equipment, medical equipment and high temperature and corrosion-resistant chemical instruments, chemical, electronics, metallurgy, building materials and national defense and other industries, the application is very extensive.

Quartz glass is often used in semiconductor industrial equipment at a high temperature of 1000 ℃ to 1300 ℃. In this state, devitrification occurs due to the attachment of impure substances. The devitrification part is the crystallization of quartz, and the transition point of crystallization is 275 ℃. When quartz glass drops from high temperature to this transition temperature, the crystalline part of surface devitrification and the quartz glass itself have different expansion coefficients between the high-temperature α phase and the low-temperature β phase. When the opaque peeling is more serious under rapid cooling, it will cause cracking.

How is the permeability of quartz glass products?
This performance of quartz glass is important for users. For example, when quartz glass is used as a high-temperature container or diffusion tube in the semiconductor industry, because the semiconductor material requires high purity, the refractory material used as a furnace lining in contact with quartz glass must undergo high temperature and cleaning treatment in advance to remove alkaline impurities such as potassium and sodium before it can be put into quartz glass for use.
