Product Description
1. Ultra-High Purity & Consistent Quality
- SiO₂ purity above 99.99%, premium grades up to 99.999%
- Extremely low impurity content — no bubbles, no stones, no striae
- No devitrification or deformation at high temperatures, ensuring a longer service life
2. Extreme Heat Resistance & Thermal Stability
- Long-term service temperature 1100°C–1200°C, short-term up to 1450°C
- Melting point approx. 1730°C, far higher than ordinary glass
- Ultra-low thermal expansion coefficient (5.5×10⁻⁷/°C); excellent thermal shock resistance — a tube at 1100°C can be plunged into cold water without cracking
3. Strong Corrosion Resistance & Chemical Inertness
- Highly stable against most acids (except hydrofluoric acid)
- Better alkali resistance than ordinary glass
- No reaction with metals at high temperatures, never contaminating materials
- Ideal for high-cleanliness applications in chemical and semiconductor industries
4. Full-Spectrum Light Transmission & Superior Optics
- High UV transmittance (full 185nm–2500nm band)
- Deep-UV transmittance far exceeding ordinary glass
- Good infrared transmittance as well
- Suitable for UV lamps, lasers and optical instruments
5. Excellent Electrical Insulation & Safe Reliability
- Excellent electrical insulation
- Maintains good dielectric properties at high temperatures
- Suitable for high-frequency, high-voltage electrical equipment
6. Complete Size Range & Customization Support
- Outer diameter range: φ1.5mm – φ300mm
- Wall thickness: 0.5mm – 10mm
- Length up to 3 meters
- Supports cutting, flame-polished ends, flanging, sealing, frosting, flange fitting and other deep processing
