Physical properties

Good light transmission performance: quartz glass has good light transmission performance in the whole spectral band from ultraviolet to infrared, the visible light transmission rate is above 93%, especially in the ultraviolet spectral region, the transmission rate can reach more than 80.
Good electrical insulation performance: the resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass, is a very good electrical insulation material, even at high temperatures also has good insulation properties.
Good thermal stability: the softening point temperature of quartz glass is about 1730℃, which can be used for a long time at 1100℃, and the short time use temperature can reach 1450℃.
High temperature resistance: the coefficient of thermal expansion of quartz glass is very small, can withstand drastic temperature changes, the quartz glass will be heated to about 1100 ℃, put into room temperature water will not blow up.
Disadvantage:Fragile.

Chemical properties

Corrosion resistance: Except for hydrofluoric acid, quartz glass almost does not react chemically with other acids, its acid resistance is 30 times that of ceramics and 150 times that of stainless steel, especially its chemical stability at high temperatures, which is incomparable to any other engineering materials.
