What Are Quartz Rods?
Quartz rods are cylindrical solid components made from high purity fused silica. Compared to quartz tubes, rods are solid and are commonly used in applications requiring structural support, optical transmission, and precision machining.
Due to their excellent purity, stability, and machinability, quartz rods are widely used in semiconductor equipment, optical systems, laboratory instruments and custom engineering components.
Key Advantages of Quartz Rods
Ultra High Purity
SiO₂ ≥ 99.99%, metal impurities < 20 ppm for contamination-sensitive environments.
High Temperature Resistance
Stable up to 1100°C continuous, short-term up to 1300°C.
Excellent Mechanical Strength
Solid structure provides better rigidity compared to hollow quartz tubes.
Thermal Stability
Low thermal expansion ensures resistance to thermal shock.
Optical Transparency
High transmission in UV, visible and infrared wavelengths.
Chemical Resistance
Resistant to most acids except hydrofluoric acid.
