6-7 feet large diameter transparent quartz tube
6-7 feet large diameter transparent quartz tube is a special industrial glass tube made of high purity silica as raw material by electrofusion or gas refining process.
Core parameters:
Diameter range: 150-300mm outer diameter coverage, wall thickness can be customized according to requirements (usually 3-15mm)
Length specifications: standard length 6 feet (about 1.83 meters) to 7 feet (about 2.13 meters), support non-standard customization
Light transmittance: visible light transmittance ≥ 93%, ultraviolet light transmittance ≥ 80%
Temperature resistance: long-term use temperature 1100 ° C, short-term temperature resistance up to 1450 ° C
Chemical stability: Except for hydrofluoric acid, it has complete corrosion resistance to all inorganic acids, organic acids and salt solutions, and its acid resistance is 30 times that of ceramics and 150 times that of stainless steel
The product adopts a stepped structure design, which effectively disperses the thermal stress in the high temperature and high pressure environment by optimizing the wall thickness distribution (thickening at the bottom and thinning at the top), and solves the cracking problem caused by the uneven thermal expansion coefficient of traditional quartz pipes. Its linear expansion coefficient is only 1/10 of that of ordinary glass, and it can withstand the extreme temperature difference from 1000 ° C directly immersed in room temperature water without cracking.
Key features and problems solved:
Extreme optical performance: with extremely high transmittance in the ultraviolet to infrared spectral range (especially in the ultraviolet region), it can efficiently transmit light and energy, solving the problems of low light transmittance and severe UV barrier of ordinary glass.
Excellent thermal stability: very low coefficient of thermal expansion, can withstand severe temperature changes (thermal shock), the maximum short-term use temperature can reach 1200 ° C, long-term use temperature is about 1100 ° C. This solves the problem of ordinary materials being easy to soften, deform or burst at high temperatures.
Exceptional corrosion resistance: It is highly resistant to most acids, alkalis, and chemicals except hydrofluoric acid and hot phosphoric acid, ensuring long life and reliability in harsh chemical environments, and solving the problem of corrosion and pollution of metal materials.
High purity and low hydroxyl content: high material purity, extremely low metal impurity content, and products with different hydroxyl (OH) content can be provided according to customer needs, effectively reducing the crystallization (loss of transparency) caused by hydroxyl groups during high temperature applications, and solving the risk of product contamination or process failure due to impure materials.
Excellent electrical insulation: It is an excellent electrical insulator, ideal for use in high-frequency or high-voltage environments.
Main application fields
With its unique comprehensive properties, 6-7 foot large diameter transparent quartz tubing is an indispensable core material for many key industries.
1. Semiconductor and photovoltaic industries
Application scenario: As a key component of semiconductor single crystal silicon, polysilicon ingot and solar photovoltaic silicon ingot growth furnace - quartz crucible protective cover/bell cover.
Problems solved:
Provide a high-temperature, high-purity clean environment to prevent molten silicon from being contaminated during growth.
The excellent light transmittance allows for the precise observation and control of the crystal growth process through an infrared monitoring system.
Its thermal stability ensures dimensional stability and safety in long-term high-temperature processes.
2. High-end lighting industry
Application scenarios: It is used to manufacture high-power metal halide lamps, xenon lamps, and UV sterilization lamps.
Problems solved:

Extremely high UV transmittance is essential for UV sterilization lamps and special curing lamps, ensuring sterilization or curing efficiency.
It provides a robust and transparent solution for high-brightness lighting.
3. Precision optics and scientific research experiments
Application scenarios: as observation windows, reaction chambers, customized experimental devices (such as CVD, PVD equipment), laser components, astronomical telescope mirror blank materials.
Problems solved:
It provides scientists with a window through which to directly observe the experimental process under extreme conditions such as high temperatures, vacuum, and corrosive atmospheres.
Its low thermal expansion characteristics ensure the stability and accuracy of the optical system.
4. Chemical and environmental protection equipment
Application scenarios: used for special corrosion-resistant reactor sight glass, pipeline, exhaust gas treatment device observation section.
Problems solved:
In strong acid, alkali or high temperature steam environments, it replaces corrosive metal sight glasses and provides a long-lasting and safe observation solution.
Transparency allows for real-time monitoring of internal reactant status and flow.
