Detail Information
5N Fused Silica Quartz Tube
Custom Large Diameter Quartz Tube for Semiconductor Diffusion Furnace and PV Cell Production
Felix Glass Co., Limited manufactures large outer diameter fused silica quartz tubes from 99.999% high-purity SiO2 material. The tube is designed for high-temperature semiconductor wafer diffusion, oxidation processes and photovoltaic solar cell production lines where low contamination and dimensional stability are critical.
Ultra-Low Impurity
5N SiO2 material supports low metal impurity control and helps reduce contamination risk for wafers and solar substrates.
Large Size Customization
Custom outer diameter, wall thickness, length, end polishing, branch tube forming and flange welding are available by drawing.
Typical Reference Values
Core Technical Specification
Final dimensions and tolerances should be confirmed according to furnace equipment drawings and working temperature conditions.
| SiO2 Purity | 99.999% 5N ultra-high purity | Outer Diameter | 100mm to 600mm custom range |
|---|---|---|---|
| Wall Thickness | 4mm to 20mm | Max Single Length | 2200mm |
| Thermal Shock | Rapid cold-hot switching resistance | Surface Treatment | Fire polished or mechanical fine polishing |
| Transmittance | UV-Vis-IR transmittance at least 93% | Impurity Control | PPb grade trace metal impurity control |
Production Workflow
Controlled Processing from Tube Blank to Clean Packaging
- High-purity silica melting and continuous drawing for large quartz tube blanks
- Fixed-length cutting, rotary flame edge polishing and stress annealing
- Ultrasonic cleaning, dimensional inspection and high-temperature aging simulation
- Dust-proof sealed packaging for cleanroom-oriented transportation
Main Application Scenarios
Semiconductor silicon wafer diffusion furnace and oxidation furnace tube
Photovoltaic monocrystalline and polycrystalline solar cell diffusion lines
High-purity gas delivery and high-temperature reaction chamber
Laboratory sintering and thermal cycling test equipment
Quality Control
Inspection Before Delivery
Each custom quartz tube can be checked for outer diameter, wall thickness, full length tolerance, bubble and scratch appearance, edge polishing quality, stress annealing result, impurity control and air tightness for welded modified structures.
Customization FAQ
What maximum outer diameter can be customized?
Typical large outer diameter customization ranges from 100mm to 600mm. Larger or special geometry requirements should be evaluated by furnace drawing.
Can both ends be processed with flanges or branch ports?
Yes. End forming, flange welding and branch tube processing can be reviewed according to assembly structure and working conditions.
Is a trial tube available for new furnace testing?
Small trial orders are available, with MOQ 1 piece for drawing-based evaluation and prototype confirmation.
