What is Fused Silica?



Fused Silica Glass Window Sheet is a high purity, colorless and transparent glass that is widely used in many scientific research and industrial applications due to its excellent physical and chemical properties.

Quartz glass is a glass with high silicon content, usually made from quartz sand and other raw materials with very high purity and thermal stability. Quartz glass offers the following advantages over other materials:

Excellent Optical Properties: Quartz glass has excellent optical properties such as high transparency, low spontaneous luminescence and low dispersion, so it is widely used in lasers, fiber-optic communications, solar cells and other fields.


High thermal stability: quartz glass can withstand temperatures up to 1000°C or more, so it is widely used in high-temperature chemical reactors, heat treatment equipment and other fields.

Excellent chemical stability: quartz glass can withstand the erosion and corrosion of most chemicals, so it is widely used in chemical, biological, medical and other fields.


Application of Fused Silica Window



Fused silica window sheets are a commonly used quartz product with the following applications:
Optical applications: quartz glass window sheets can be used as optical components for lasers, telescopes, microscopes, spectrometers, etc.
Chemical applications: quartz glass window pieces can be used for chemical reactors, test tubes, penetrators, etc.
Electronic applications: quartz glass windows can be used to make solar cells, semiconductor devices and so on.
Fused quartz glass window sheet is a high-purity, high-performance quartz product that is widely used in many scientific research and industrial applications.

Fused Silica Windows is stronger than N-BK7 optical windows, it have better homogeneity, lower coefficient of thermal expansion, it can be used at temperatures up to 1050°C.
