High-purity quartz material refers to quartz material with a purity of SiO₂ ≥ 99.998%, with a total impurity content of less than 20 ppm, which is made from high-purity quartz sand through purification and other processes.
Advantages: ① Excellent transmittance from ultraviolet to infrared wavelengths, low thermal expansion coefficient, melting point up to 1713℃, strong resistance to high temperatures and thermal shock
② It has good chemical stability, except that it is not resistant to hydrofluoric acid
③ It boasts extremely high resistivity and excellent insulation performance, making it suitable for high-frequency and high-voltage environments
