Polishing Clear Quartz Glass Tube 300mm For Pyrolysis Furnace High Purity
Optical Instrument Use Quartz Glass Tube With High Light Transmittance
Applications
Quartz glass tubes are widely used in various lighting applications including sterilization lamps, mercury lamps, metal halide lamps, diffusion tubes, protection tubes, optical instruments, sight glasses, observation windows for furnaces, semiconductor manufacturing, photoelectronics, military industry, metallurgy, and water treatment systems.
Key Performance Characteristics
High Temperature Resistance: Quartz glass hardening temperature approximately 1730°C. Suitable for long-term use at 1100°C with maximum short-term temperature resistance up to 1450°C.
Excellent Light Transmission: Superior transmittance across all spectral bands from purple to red. Visible light transmittance exceeds 93%, with ultraviolet spectral region transmittance over 80%.
Corrosion Resistance: Exceptional chemical stability, resistant to all acids except hydrofluoric acid. Acid resistance is 30 times that of ceramic and 150 times that of stainless steel.
Superior Thermal Stability: Low thermal contraction coefficient withstands severe temperature changes. Can be heated to 1100°C and immersed in cold water without cracking.
