High Purity Quartz Rod / Fused Silica Rod - China Supplier & Factory for Semiconductors and Laboratory Use

Quartz rods are high-performance cylindrical components crafted from fused silica (SiO₂ ≥ 99.99%), renowned for their exceptional high-temperature resistance, with a softening point of approximately 1730°C and a long-term usability at 1100°C. These rods boast excellent UV-IR transmittance, low thermal expansion, and remarkable chemical inertness, making them resistant to most acids, except HF. Additionally, they provide outstanding electrical insulation properties. Perfect for applications in optics, semiconductors, lasers, laboratory instruments, and high-temperature equipment, quartz rods are essential materials for precision manufacturing and harsh-environment scenarios. As a leading supplier and factory in China, we ensure premium quality quartz rods to meet diverse industrial needs.

Produced through the melting of natural or synthetic quartz and formed into solid cylindrical rods via drawing or molding processes, our quartz rods are ideal semi-finished materials that can be further fabricated into tubes, supports, or optical components.

❓ Frequently Asked Questions

🔹 What cross-sectional dimensions are available in this specification table?

The table covers eight standard cross-sectional sizes ranging from 3×3 mm up to 20×20 mm, including 3×3, 4×4, 5×5, 6×6, 8×8, 10×10, 15×15, and 20×20.

🔹 What are the tolerance values for smaller cross-sectional sizes such as 3×3 to 5×5?

For smaller sizes including 3×3, 4×4, and 5×5, the dimensional tolerance is ±0.1 mm, ensuring a high level of precision for fine applications.

🔹 Do tolerances increase as the cross-sectional size gets larger?

Yes. Tolerances gradually increase with size. Sizes 6×6 and 8×8 carry a tolerance of ±0.15 mm, sizes 10×10 and 15×15 have ±0.2 mm, and the largest size 20×20 has a tolerance of ±0.25 mm.

🔹 What standard lengths are available for sizes up to 10×10?

Cross-sectional sizes from 3×3 through 10×10 are available in standard lengths ranging from 100 mm to 1000 mm, providing flexible options for various applications.

🔹 Are the standard lengths different for larger sizes like 15×15 and 20×20?

Yes. For larger cross-sectional sizes of 15×15 and 20×20, the standard length range is reduced to 100–500 mm, compared to the 100–1000 mm range available for smaller sizes.

🔹 Can custom lengths or tolerances be requested outside of these standard specifications?

The table reflects standard production specifications. For requirements outside these listed dimensions, tolerances, or lengths, it is recommended to contact the supplier directly to discuss custom manufacturing options.
