haracteristic:
1.High temperature resistance
The softening point temperature of quartz glass is about ***0 � C,
which can be used for a long time at ***0 C, and the maximum
temperature for short time can reach ***0 C.
2.Corrosion resistance
With the exception of hydrofluoric acid, quartz glass has almost no
chemical reaction with other acids. Its acid resistance is *0 times
that of ceramics and **0 times that of stainless steel, especially
the chemical stability at high temperatures, which is impossible
for any other engineering materials.
3.Good thermal stability
The thermal expansion coefficient of quartz glass is extremely
small, and it can withstand severe temperature changes. The quartz
glass is heated to about ***0 � C and will not burst when placed in
normal temperature water.

4.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 above *3%, especially in the ultraviolet spectral
region, and the maximum transmittance can reach more
than*0.
5.Good electrical insulation performance
The resistance value of quartz glass is equivalent to *0,**0 times
that of ordinary glass. It is an excellent electrical
insulation material and has good insulation properties even at high
temperatures.
Application:
Quartz glass is widely used in electric light source,
semiconductor, optical communication, military industry,
metallurgy,
building materials, chemical, machinery, electric power,
environmental protection and other fields due to its excellent
physical and chemical properties.
