Characteristics of Quartz Glass Tube

Glass is a widely used inorganic non-metallic material with a wide range of applications. It can be used in construction, daily use, art, instrumentation and other fields. In addition to the commonly used tempered glass and printed glass, there are also optical fiber, dimming glass and other types that are technically demanding. In this article we will introduce the characteristics of quartz glass tubes.

1.Characteristics of quartz glass tube

(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. The short-time use temperature can reach 1450 ° C.

(2)Corrosion resistance

In addition to hydrofluoric acid, quartz glass hardly reacts with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Especially at high temperatures, it is impossible for any other engineering materials. Comparable.

(3)Good thermal stability

Quartz glass has a very small thermal expansion coefficient and 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 range from ultraviolet to infrared, and the visible light transmittance is above 95%, especially in the ultraviolet spectral region, the transmittance can reach more than 80%.

(5)Good electrical insulation performance

Quartz glass has a resistance value equivalent to 10,000 times that of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even at high temperatures. Quartz glass has been widely used in various fields such as electric light source, semiconductor, optical communication, military, metallurgy, building materials, chemistry, machinery, electric power, and environmental protection because of its excellent physical and chemical properties.
