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.
