Quartz windows are usually cut and ground from quartz glass, and their silica content can reach more than 99.99%. The hardness is seven grades, and it has the characteristics of high temperature resistance, low thermal expansion coefficient, thermal shock resistance and good electrical insulation performance. The visible light transmittance of the quartz window is over 85%. Quartz glass can be divided into two categories, fused silica glass and synthetic silica glass, from the large production range. Heat resistance, light transmittance, electrical insulation, and chemical stability are all very good.
