Quartz glass tube, which made of silicon dioxide, is a special industrial technology glass and a very good base material. Quartz glass has a series of excellent physical and chemical properties.

1. High temperature resistant

Quartz glass’s softening point temperature is about 1730 °C. It can be used for a long time under 1100 °C, a short period of time for the highest temperature 1450 °C.

2. Corrosion resistant

Quartz glass is almost not reacting with other acids except hydrofluoric acid. The acid capacity is 30 times of the ceramic, is 150 times of stainless steel. Its chemical stability at high temperature, in particular, is unmatched by any other engineering materials.

3. Good thermal stability

Quartz glass’s small thermal expansion coefficient makes it can withstand the severe temperature changes. It will not burst into cold water when quartz glass heated to 1100 °C or so.

4. Pervious to light performance is good

Quartz glass in the ultraviolet radiation to the whole spectrum of infrared wave band has better performance of pervious to light; visible light transmittance over 93%, especially in the ultraviolet spectral region, the maximum transmittance can reach more than 80%.

5. Electric insulation performance is good

Quartz glass resistance value is equivalent to ten thousand times of common glass, is an excellent electric insulation material, has good performance even under high temperature. Quartz glass because of the excellent physical and chemical properties thus has been widely used in electric light source, semiconductor, optical communications, military industry, metallurgy, building materials, chemical, machinery, electricity, environmental protection and other fields.
