high temperature proof , chemical stability , perfect insulation, stable ultrasonic delay , best spectrum

Quartz plate is a special glass that contains silicon dioxide .Our quartz glass board is made from natural quartz after the process of melting and fine grinding .It is transparent and colorless, contains no air bubble and no processing trade will be found . It is purity is controlled to the grade of  PPM.
