Polishing frosted quartz rod is a customized industrial component made from high-purity quartz sand through melting, forming, precision processing, and surface treatment (polishing or frosted). Its unique high temperature resistance, low thermal expansion coefficient, excellent optical properties, and chemical stability make it a core material in the fields of semiconductors, optoelectronics, laboratory equipment, and high-temperature processes. We focus on providing customized quartz rod solutions for global customers, meeting the demanding requirements of different industries for dimensional accuracy, surface treatment, and functionality.

Product application areas

1. Semiconductor manufacturing: used for wafer carriers, diffusion furnace tubes, cleaning tank supports, etc., resistant to high temperature etching environments.  

2. Optoelectronic industry: As a supporting structure or transparent component for ultraviolet infrared optical devices, it ensures the stability of laser systems.  

3. Laboratory equipment: observation windows for high-temperature reaction vessels, precision instrument supports to ensure the accuracy and reproducibility of experimental data.  

4. Industrial heating system: The insulation support rod of the high-temperature furnace will not deform or pollute the process environment after long-term use.  

Core advantages of the product

1. Ultimate purity and stability

-The purity of the raw material is above 99.99%, avoiding the precipitation of impurities at high temperatures that may affect the process results.  

-The coefficient of thermal expansion is as low as 5.5 × 10 ⁻⁷/℃, and its thermal shock resistance far exceeds that of ordinary glass or ceramics.  

2. Precision machining capability

-The diameter tolerance can be controlled within ± 0.02mm, and the surface roughness Ra is ≤ 0.4 μ m (polished) or 0.8-1.2 μ m (frosted).  

-Support non-standard customization: irregular cutting, drilling, grooves, special end treatment, etc.  

3. Multi functional surface treatment

-Polishing surface: transmittance>93% (@ 200nm-2.5 μ m), reducing light scattering loss.  

-Matte surface: enhances mechanical adhesion and avoids adhesion problems in high-temperature equipment.  

4. Environmental adaptability

-Temperature resistance range: -100 ℃ to 1250 ℃, instantaneous heat resistance can reach 1450 ℃.  

-Resistant to acid and alkali corrosion (excluding hydrofluoric acid), suitable for highly corrosive working conditions.  

Key issues to be addressed

-Alternative metal materials: eliminate high-temperature oxidation and magnetic interference issues, and improve semiconductor process yield.  

-Overcoming the limitations of glass: By utilizing its low thermal expansion properties, it avoids the risk of rupture caused by sudden temperature changes.  

-Customized demand response: For special equipment structures, we provide fast sampling and bulk delivery to shorten customer research and development cycles.    

Customer case (anonymous processing)

-Case 1: A European semiconductor equipment supplier needs to develop a transparent quartz support rod that can withstand 1100 ℃ within 3 months, with a requirement of straightness ≤ 0.05mm. We optimized the annealing process and delivered the product with zero failures in high-speed transmission testing for customers, resulting in a 12% increase in yield.  

-Case 2: The original stainless steel bracket used by North American laser companies caused UV attenuation. After replacing it with our polished quartz rod, the optical path efficiency increased by 18% and the service life was extended by three times.
