What are the Features of Quartz Glass?
Very High Working Temperature: Between 1200°C and 1300°C.Corrosion-Resistant: Except hydrofluoric acid and high concentration phosphoric acid, it barely has reacting with any other acids.Excellent Thermal Stability: No bursting when quickly putting a 1100°C of quartz tube in cold water.Excellent Optical Performance: UV transmittance at over 85% and light transmittance at over 95%.Electrical Insulation Performance: Its resistance value is equivalent to 10,000 times of ordinary glass even under high temperature conditions.
