Boron Nitride Ring

Boron Nitride Rings are specially designed sealing and insulation components for extreme temperature applications. Produced from high-purity boron nitride ceramic, these rings maintain excellent dimensional stability and electrical insulation properties in high-temperature environments, outperforming traditional graphite and ceramic rings through their unique combination of thermal and mechanical properties.

Key Features:

• Exceptional Thermal Stability - Maintains structural integrity and dimensional stability at temperatures up to 2000°C in inert atmospheres.

• Excellent Sealing Performance - Low friction coefficient and thermal expansion provide reliable sealing in high-temperature vacuum and pressure systems.

• Superior Electrical Insulation - Volume resistivity >10¹⁴ Ω·cm ensures reliable electrical isolation in high-temperature applications.

• Outstanding Thermal Shock Resistance - Withstands rapid temperature changes up to 1500°C without cracking or degradation.

• Chemical Inertness - Highly resistant to most molten metals, slags, and corrosive chemicals, ensuring long service life.

• Precision Dimensional Control - Maintains concentricity within 0.01 mm and dimensional tolerances within ±0.02 mm.
