Характеристики
Quartz glass
Not easy to corrode under high temperature
High hardening temperature, not easy to react chemically with other substances, can be used for a long time Good thermal stability, small expansion coefficient of quartz glass, can withstand severe temperature
changes, heat the quartz glass to about 1100 ℃, put it in normal temperature water without bursting phenomenon
changes, heat the quartz glass to about 1100 ℃, put it in normal temperature water without bursting phenomenon
Good light transmittance
Quartz glass has good light transmittance in the entire wavelength range from ultraviolet to infrared, and the visible light
transmittance is above 92%, especially in the ultraviolet spectral region, the light transmittance can reach above 80%
transmittance is above 92%, especially in the ultraviolet spectral region, the light transmittance can reach above 80%
Good electrical insulation performance
The resistance value of quartz glass is 10,000 times that of ordinary glass. It is a good electrical insulating material and has good electrical properties even at high temperatures.
