Because quartz glass has unique comprehensive properties that other materials do not have, that is, very low thermal conductivity, excellent thermal vibration resistance, high deformation temperature and softening temperature, very low thermal conductivity, very low dielectric loss and optical transmittance in a very wide spectral range from ultraviolet to infrared, quartz glass is made into various parts and is widely used in various fields.
Features of product:
* High purity quartz with Silica content 99.99% or above.
* Very low thermal conductivity, excellent thermal vibration resistance
* Very high deformation temperature and softening temperature
* High dielectric electric field strength, low dielectric loss, and low conductivity
* Optical transmittance in an extremely wide spectral range from ultraviolet to infrared
* Very good chemical stability, does not react with water, salt solutions and most acids.
* Excellent radiation resistance.
