Quartz Glass Tubes | Professional Fused Quartz Tube Manufacturer in China
FGQuartz supplies high-purity quartz glass tubes and fused quartz tubing in standard, large diameter, thin-wall, capillary and opaque forms, plus UV- and IR-transmitting grades. Used in semiconductor diffusion and oxidation furnaces, UV systems, fiber drawing and laboratory furnaces, tubes are supplied cut to length with controlled wall thickness and concentricity.
What Are Quartz Glass Tubes?
Quartz glass tubes are cylindrical components made from high purity fused silica, also commonly known as fused quartz tube products. 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 glass tubes are widely used in semiconductor processing, high-temperature furnaces, UV systems and precision laboratory environments – making them the core material for semiconductor quartz tube and lab high-temperature quartz tube applications.
Key Advantages of Our Quartz Glass Tubes & Fused Quartz Tube Products
Ultra High Purity
SiO₂ ≥ 99.99%, metal impurities < 20 ppm — ensuring contamination-free performance for semiconductor and other critical applications.
High Temperature Resistance
Stable operation up to 1200°C (continuous), short-term up to 1300°C — ideal for high-temperature laboratory and industrial environments.
Low Thermal Expansion
Excellent resistance to thermal shock and rapid temperature changes, a core advantage of our premium product range.
Optical Transparency
High transmission in UV, visible and infrared spectrum for optical-grade tubes.
Chemical Stability
Resistant to most acids except hydrofluoric acid, suitable for harsh laboratory and industrial environments.
Electrical Insulation
Maintains strong dielectric performance at high temperatures, perfect for high-voltage industrial applications.
