High Purity Fused Quartz Cone High Temperature Resistance Industrial with Precision Taper Angle

1. Ultra-High Purity – Zero Contamination

• SiO₂ purity ≥ 99.99%, premium grades up to 99.999%
• Extremely low impurity content — no bubbles, no stones
• No devitrification, volatilization or slagging at high temperatures
• Material of choice for high-cleanliness processes in semiconductor and photovoltaic industries

2. Extreme Heat Resistance – Outstanding Thermal Stability

• Long-term service temperature 1100°C – 1200°C
• Withstands short-term exposure to 1450°C
• Ultra-low thermal expansion coefficient (5.5×10⁻⁷/°C)
• Resists thermal shock — no cracking under sudden temperature changes

3. Precise Taper Angle – Controlled Dimensions

• High cone angle accuracy, custom machined to drawings
• Smooth inner and outer surfaces; streamlined design reduces fluid resistance
• Tight dimensional tolerances (±0.1mm level)
• Meets precise installation requirements of various equipment

4. Strong Corrosion Resistance – Chemical Inertness

• Resists strong acids (except hydrofluoric acid) and weak alkalis
• No reaction with most chemicals at high temperatures
• Ideal for directing and spraying corrosive gases / liquids
• Service life far exceeds stainless steel, ceramics and other materials

5. Excellent Light Transmission – Optically Usable

• High transmittance across the full UV-to-IR spectrum
• Usable in optical conical light-guiding and light-concentrating systems
• Low optical loss and uniform light transmission

6. Complete Size Range – Deep Customization

• Types: solid cone, hollow cone, cone tube, cone funnel, nozzle
• Cone angle: 5° – 120°, any angle customizable
• Dimensions: OD φ5mm – φ200mm, length per request
• Processing: polishing, frosting, drilling, flanging, threaded connections
• Wall thickness: uniform and controllable, as thin as 0.5mm
