High Purity Quartz Tubes Manufacturer
FGQuartz specializes in manufacturing high precision fused quartz tubes (SiO₂ ≥ 99.99%) for semiconductor, furnace, UV and laboratory applications. With strict purity control, advanced processing technology and full customization capability, we deliver reliable quartz tubing solutions worldwide.
What Are Quartz Tubes?
Quartz tubes are cylindrical components made from high purity fused silica. Compared with ordinary glass, quartz offers superior thermal resistance, chemical stability and optical transmission.
Due to its ultra-low impurity level and excellent physical properties, quartz tubing is widely used in semiconductor processing, high-temperature furnaces, UV systems and precision laboratory environments.
Key Advantages of Quartz Tubes
Ultra High Purity
SiO₂ ≥ 99.99%, metal impurities < 20 ppm, ensuring contamination-free performance.
High Temperature Resistance
Stable operation at 1100–1200°C, short-term up to 1500°C.
Low Thermal Expansion
Excellent resistance to thermal shock and rapid temperature changes.
Optical Transparency
High transmission in UV, visible and infrared spectrum.
Chemical Stability
Resistant to most acids except hydrofluoric acid.
Electrical Insulation
Maintains strong dielectric performance at high temperatures.
