Quartz Characteristic

1. Transmittance good performance Compare to ordinary silicate glass, transparent quartz glass in the whole wavelength head excellent permeability. In the infrared spectrum through than ordinary glass; in the visible region, quartz glass transmittance is relatively high ,above 85%-90%.
2. Good electrical insulation properties Quartz glass with high dielectric strength and very low electrical conductivity, even in bhigh temperature, high pressure and high frequency, it can still maintain high dielectric strength and resistance.
3. Thermal stability The thermal expansion coefficient of quartz galss is extremely small, it can be able to adapt drastic temperature changes
