Quartz glass tube

1.High temperature resistance

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 be as high as 1450℃.

2. Corrosion resistance

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

3. Good thermal stability

The coefficient of thermal expansion of quartz glass is extremely small, and it can withstand drastic temperature changes.

4. Good light transmission performance

Quartz glass has good light transmission performance in the whole spectral band from ultraviolet to infrared, and the visible light transmission rate is above 95%, especially in the ultraviolet spectrum, the transmission rate can be more than 80%.

5. Good electrical insulation performance

The resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass, is an excellent electrical insulation material, even at high temperatures also has good electrical properties.　Due to the above excellent physical and chemical properties, quartz glass is widely used in various fields such as electric light source, semiconductor, optical communication, military industry, metallurgy, building materials, chemical, machinery, electric power, environmental protection, etc.
