Quartz Tubes for High-Temperature & Optical Service

Quartz tubes are hollow cylindrical components made from high-purity fused silica (SiO₂). They are characterized by excellent thermal shock resistance, low coefficient of thermal expansion, high chemical purity, and outstanding optical transmission from ultraviolet to infrared wavelengths.

These tubes are widely used as heating element enclosures, furnace tubes, reactor chambers, sight glasses, and protective sheaths in semiconductor manufacturing, laboratories, lighting and various high-temperature industrial processes. The combination of high purity and thermal stability makes quartz tubes ideal for applications where contamination must be minimized.

We supply quartz tubes for overseas distributors, industrial buyers, equipment manufacturers, research institutions and OEM customers, with different grades, diameters, wall thicknesses, lengths and custom fabrication available according to specification.

High-Temperature Resistance Continuous use up to 1100°C, short-term up to 1200°C depending on grade.
Low Thermal Expansion Coefficient of thermal expansion ~5.5×10⁻⁷/°C, providing excellent thermal shock resistance.
High Optical Transmission Transparent from UV (185 nm) to IR (2500 nm) depending on grade.
High Chemical Purity SiO₂ content ≥ 99.99% for high-purity grades, suitable for semiconductor and lab use.

    Frequently Asked Questions About Quartz Tubes

    What is a quartz tube?
    A quartz tube is a hollow cylindrical component made from high-purity fused silica (SiO₂). It combines high temperature resistance, low thermal expansion, optical clarity and chemical inertness.
    What is the temperature range of quartz tubes?
    Quartz tubes can withstand continuous temperatures up to 1100°C (transparent) or 1000°C (opaque), with short-term tolerance up to 1200°C. The softening point is about 1680°C.
    What is the difference between transparent and opaque quartz tubes?
    Transparent quartz tubes offer high optical transmission from UV to IR and are used where visibility or light transmission is needed. Opaque quartz tubes have a milky white appearance, better thermal insulation and are often more economical for heating applications.
    What is the purity of quartz tubes?
    High-purity quartz tubes typically have SiO₂ content ≥ 99.99%. Standard grades have ≥ 99.9%. The purity level affects contamination and optical properties.
