Quartz rod is a high-performance cylindrical product made of fused silica (SiO₂ ≥ 99.99%). It features exceptional high-temperature resistance (softening point ~1730°C, long-term use at 1100°C), excellent UV-IR transmittance, low thermal expansion, and superb chemical inertness (resistant to most acids except HF). It also offers outstanding electrical insulation. Widely used in optics, semiconductors, lasers, lab high purity fused silica quartz rod for semiconductor laboratory instruments, and high-temperature equipment, it is an essential material for precision and harsh-environment applications.
A quartz rod is a cylindrical component made from high-purity silicon dioxide (SiO₂). It is produced by melting natural or synthetic quartz and forming it into solid rods through drawing or molding processes.
Quartz rods serve as basic semi-finished materials for further fabrication into tubes, supports, or optical components.
