Product Description

Material & Quality

Made from 99.99% high-purity fused silica, our large-diameter quartz tube is free of impurities, ensuring minimal thermal expansion and maximum resistance to thermal shock (can withstand rapid temperature changes from -20℃ to 1200℃). It is non-toxic, non-porous, and resistant to most acids (except hydrofluoric acid) and alkaline solutions, making it suitable for corrosive chemical processing.

Core Advantages

Superior thermal stability: Operates continuously at 1100℃, short-term use up to 1450℃
Excellent mechanical strength: High compressive strength and impact resistance, cracking during installation and use
Customization support: Cut-to-length, flanged ends, and drilled holes available per customer drawings
Long service life: Resists aging and oxidation even under prolonged high-temperature exposure

Key Application Fields of Large-Diameter Quartz Tubes

Large-diameter quartz tubes are essential components in various high-end industries, thanks to their excellent thermal stability, chemical inertness and high light transmittance.

Semiconductor Industry

They are widely used in diffusion furnaces, oxidation furnaces and ion implantation equipment for wafer processing. The high purity and corrosion resistance of quartz tubes can ensure no pollution to semiconductor materials during high-temperature processes.
Solar Energy Sector

Applied to the production line of photovoltaic cells and silicon wafers, they serve as the core components of high-temperature sintering and coating equipment, helping to improve the conversion efficiency of solar cells.
High-Temperature Heat Treatment & Metallurgy

Used as furnace linings and heating chambers in annealing furnaces, quenching furnaces and sintering furnaces, they can withstand continuous high-temperature operation up to 1100℃ and resist thermal shock.
Laboratory & Scientific Research

Employed in high-temperature chemical reactors, vacuum tubes and chemical vapor deposition (CVD) systems, suitable for harsh experimental environments such as strong acid corrosion and high-temperature pyrolysis.
Optical Fiber & Optoelectronics Industry

Serve as protective sleeves and drawing molds in optical fiber preform production, ensuring the purity and uniformity of optical fiber materials during the high-temperature drawing process.
Environmental Protection & Waste Treatment

Used in high-temperature waste gas incinerators and hazardous waste treatment equipment, taking advantage of their high-temperature resistance and chemical stability to decompose harmful substances.
