Fused Silica Coils for Condensers

Quartz glass is a single-component glass of silica, which is usually divided into two categories: transparent quartz glass and opaque quartz glass (fused silica). Transparent quartz glass has only a few bubbles and has high optical uniformity and transparency. It is made of silicon tetrafluoride melted at high temperature in a crystal box. The content of SIO2 is above 99.95%, and the content of high-purity quartz glass is 99.999%. . Opaque quartz glass is made of veined quartz and quartz sand, which are melted at high temperature. It contains over 99.5% SIO2.

feature:
1. High temperature resistance
The softening point temperature of quartz glass is about 1730°C, it can be used for a long time at 1100°C, and the maximum temperature can reach 1450°C for short-term use.

2. Corrosion resistance
Quartz glass has almost no chemical reaction with other acids except hydrofluoric acid. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel, especially its chemical stability at high temperature is unmatched by any other engineering materials.

3. Good thermal stability
Quartz glass has an extremely small coefficient of thermal expansion and can withstand severe temperature changes. Quartz glass is heated to about 1100°C, and it will not burst when placed in room 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, the maximum transmittance can reach more than 80.

5. Good electrical insulation performance
The resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass. This is an excellent electrical
Insulating material, which has good insulating properties even at high temperatures.

application:
Quartz glass is widely used in electric light sources, semiconductors, optical communications, military industry, metallurgy,
Building materials, chemical industry, machinery, electric power, environmental protection and other fields due to its excellent physical and chemical properties.
