Physical properties edit broadcast
1, good thermal stability
The thermal expansion coefficient of quartz glass is very small, can withstand drastic temperature changes, the quartz glass is heated to about 1100 ° C, and will not burst into normal temperature water.
2, good light transmission performance
Quartz glass has good light transmission performance in the entire spectral band from ultraviolet to infrared, and the visible light transmittance is more than 93%, especially in the ultraviolet spectral region, the maximum transmittance can reach more than 80%.
3, good electrical insulation performance
The resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass, which is an excellent electrical insulating material and has good insulation properties even at high temperatures.
Because of its excellent physical and chemical properties, quartz glass is widely used in various fields such as electric light source, semiconductor, optical communication, military, metallurgy, building materials, chemistry, machinery, electric power, environmental protection and so on.
4. Disadvantages: fragile.
