Transparent round bottomed quartz glass rod
What can transparent round bottom quartz glass rod solve for you?
Q: As a precision instrument manufacturer, are you looking for a transparent support material that can maintain stability in high temperature and strong corrosive environments?
Answer: Our transparent round bottom quartz glass rod is designed for this purpose - it provides excellent thermal stability and chemical inertness, ensuring that your instrument can still operate accurately under extreme conditions.
Q: Are you troubled by the inability of standard sized quartz rods to meet special designs?
Answer: We offer fully customized sizes, diameters, and rounded bottoms that perfectly match your unique device structure, eliminating design compromises.
Q: Are you concerned about material impurities affecting product yield in optical or semiconductor processes?
Answer: We use high-purity quartz sand (SiO ₂ content ≥ 99.99%) to ensure low bubbles and impurities, providing reliable support for high-end applications.
Q: Do you want to reduce production interruptions caused by differences in material batches?
Answer: We ensure consistent performance of each batch of products through standardized quality control and strict production processes, helping you achieve stable and continuous production.
Transparent round bottom quartz glass rod is a cylindrical rod made of high-purity fused silica by high temperature precision processing, with a uniform arc structure at the bottom. Its unique round bottom design avoids stress concentration at right angles, enhances mechanical strength and thermal shock stability, and is widely used in laboratories, semiconductors, optics, medical devices, and industrial equipment fields.
Key features and advantages
1. Excellent thermal performance
-High temperature resistance up to 1200 ℃ (short-term), long-term use temperature of 1100 ℃
-Extremely low coefficient of thermal expansion (5.5 × 10 ⁻⁷/℃), excellent thermal shock resistance
-Round bottom design disperses thermal stress and reduces the risk of cracking at high temperatures
2. Excellent chemical stability
-Resistant to most acids, bases, and solvents except hydrofluoric acid and hot phosphoric acid
-Smooth and dense surface, not easily contaminated, easy to clean
3. Excellent optical and physical properties
-Transmittance of over 93% (ultraviolet to near-infrared band)
-High hardness (Mohs 7), good wear resistance
-The round bottom structure enhances the flexural strength, which is about 30% higher than that of a flat bottom rod
4. High purity and consistency
-Raw material SiO ₂ purity ≥ 99.99%, key impurities (Fe, K, Na, etc.) content<10ppm
-Using CNC precision machining, the diameter tolerance can be controlled within ± 0.05mm
Specifications and Customization Services
We provide comprehensive customized production to meet the needs of different industries:
-Size range
-Diameter: 1mm to 150mm
-Length: 10mm to 3000mm
-Circular base curvature: R value customization (standard R is 1-2 times the diameter)
-Surface treatment options
-Polishing treatment (optical grade, instrument grade)
-Flame polishing and sanding treatment
-Scale markings or special coatings can be applied according to requirements
-Material grade
-JGS1 (UV grade, excellent UV transmittance)
-JGS2 (optical grade, high transparency in visible light band)
-JGS3 (infrared grade, suitable for infrared optical systems)
Typical application scenarios
1. Semiconductor and Photovoltaic Industry
-Wafer carrier rod, diffusion furnace pillar, CVD equipment support
-Case: A German photovoltaic equipment manufacturer used our Φ 25mm round bottom quartz rod as a silicon wafer transmission track, which solved the deformation problem at high temperatures and increased the yield rate by 8%
2. Laboratory and research instruments
-Stirring rod, reactor support, optical bracket, high-temperature window component
-Case: A French research institution customized a Φ 8mm quartz rod with a scale for high-temperature reaction observation, achieving continuous experiments for up to 2000 hours without failure
3. Optics and Lighting Field
-Optical system support column, special lamp light guide rod, laser equipment components
-Case: Japanese optical companies use our polished Φ 12mm quartz rod as the light guide structure for UV-LED arrays, reducing light efficiency loss to within 2%
4. Medical Devices and Chemicals
-Observation window pillar and corrosive medium measurement probe bracket for pharmaceutical reactors
-Case: American biotechnology company uses our customized quartz rod as the internal sensor bracket for the bioreactor, which can withstand repeated high-temperature sterilization and extend its lifespan by three times
