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
