Characteristic

1.High temperature resistance

The softening point temperature of quartz glass is about 1730 ° C, which can be used for a long time at 1100 C, and the maximum temperature for short time can reach 1450 C.

2.Corrosion resistance

With the exception of hydrofluoric acid, quartz glass has almost no chemical reaction with other acids. Its acid resistance is 30 times that of ceramics and 150 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 1100 ° 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 93%, especially in the ultraviolet spectral region, and the maximum transmittance can reach more than80.

5.Good electrical insulation performance

The resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass. It is an excellent electrical
insulation material and has good insulation properties even at high temperatures.
