In semiconductor and photovoltaic (PV) industry, the whole range of quartz glass
Components are used for the fabrication of quartz washing tanks and quartz boats for
Wafer cleaning and many other applications with a working temperature up to 800 degree. Du
To the elevated sodium (Na), quartz plate cannot be used for high temperature applicatio
With a steady temperature up to 1100 degree. The sodium will cause glass devitrification. We
Are pleased to offer you a sample of the material to test the suitability of the material for
Your individual application.
In lighting
Because of its high purity, EN08 has an excellent transmission in the UVC range of 200-
280nm wavelength. By vacuum annealing, the OH content of plate can be lowered to 20-
30ppm. Quartz plate is a good material for UVC disinfection.
Also quartz plates are used in other UV applications such as cover plates for UV curing
Systems and lower optical applications.
Fabrication of the plates
