What are the application fields of quartz glass?

        Quartz glass is usually smelted and cut and ground from quartz, and its silica content can reach more than 99.99%. The hardness is Mohs 7, and it has the characteristics of high temperature resistance, low thermal expansion coefficient, thermal shock resistance and good electrical insulation performance. Usually colorless and transparent, the visible light transmittance is more than 85%. As a quartz glass company, today I will talk to you about the application fields of quartz glass.

        Quartz tubes are drawn through vertical continuous melting. Domestic state-owned enterprises and individual private companies introduced European equipment 30 years ago. After 30 years of development, conventional-sized quartz tubes have become very mature. The processing of quartz glass is traditionally realized by cutting quartz mounds or cutting and flattening quartz tubes. Quartz is not a metal, and all the links involving horizontal cutting and grinding are very troublesome and the cost remains high. Relatively low-cost continuous melting and drawing of quartz plates is a technology within 10 years, and so far only a few companies have been able to achieve it, and the yield is still low, so the cost will not be low.

        Quartz glass has a wide range of applications. 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. And the quartz sheet has high precision, no bubbles, smooth surface, corrosion resistance, good light transmittance, especially suitable for optical, electronic, chemical, military and other optical instrument observation windows.
