Product Description
Clear Quartz Glass roducts
Quartz glass is a single-component glass of silicon dioxide, which is usually divided into two categories: transparent quartz glass and opaque quartz glass (fused silica). Transparent quartz glass has only a small amount of air bubbles, and has a very high optical uniformity and transparency. It is made of silicon tetrafluoride in a crystal box and melted at high temperature. The SIO2 content is above 99.95%, and the high-purity quartz glass content is 99.999%. . Opaque quartz glass is used vein quartz, quartz sand as raw material, and it is melted at high temperature. It contains more than 99.5% SIO2.
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.
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.
