As a kind of special industrial technology glass made of high-purity silica as the main raw material, quartz tubes are widely used in many fields due to their unique physical and chemical properties, especially in the lighting industry. Quartz tubes play an indispensable role.

Basic characteristics of quartz tubes

Quartz tubes have a range of excellent physical and chemical properties, including:

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

Corrosion resistance: Except for hydrofluoric acid, quartz glass hardly reacts chemically with other acids, and its acid resistance is 30 times that of ceramics and 150 times that of stainless steel.

Good thermal stability: quartz glass has a very small coefficient of thermal expansion and can withstand severe temperature changes. After being heated to around 1100 ° C, it will not burst when placed in room temperature water.

Good light transmittance: Quartz glass has good light transmittance in the entire spectral band from ultraviolet to infrared, with a visible light transmittance of over 93%, especially in the ultraviolet region, with a maximum transmittance of over 80%.

Good electrical insulation performance: The resistance value of quartz glass is equivalent to ten thousand times that of ordinary glass, making it an excellent electrical insulating material, even at high temperatures.

The application of quartz tubes in the lighting industry

Due to its excellent light transmission and high temperature resistance, quartz tubes are widely used in the lighting industry, including the following aspects:

Halogen lamp: Halogen lamp is a kind of high-brightness and high-efficiency lamp, which is widely used in stage lighting, automotive headlamps, photographic lighting and other fields.
