Description:

Boron Nitride (BN) break rings are high-performance ceramic components designed for applications requiring excellent thermal stability, chemical resistance, and electrical insulation. These rings play a crucial role in high-temperature processes, particularly in molten metal handling, where their non-wetting properties prevent metal adhesion and ensure smooth operation.

Key Features:

  • High Thermal Stability – Withstands extreme temperatures up to 2,000°C in inert atmospheres.
  • Exceptional Chemical Resistance – Inert to most acids, alkalis, and molten metals, preventing corrosion.
  • Non-Wetting Properties – Prevents adhesion of molten metals, ideal for continuous casting applications.
  • Low Thermal Expansion & High Thermal Conductivity – Provides excellent thermal shock resistance.
  • Superior Electrical Insulation – High dielectric strength and low dielectric constant for electrical applications.
  • Easy Machinability – Can be customized into precise shapes for specific industrial requirements.

Applications:

  • Molten Metal Processing – Used in continuous casting and metal forming to prevent metal adhesion and ensure smooth flow.
  • Semiconductor & Electronics – Applied in high-temperature plasma environments and electrical insulation applications.
  • Aerospace & Defense – Ideal for thermal protection systems and high-temperature structural components.
  • Vacuum & High-Temperature Furnaces – Serves as a protective component in extreme heat environments.
  • Glass & Ceramic Manufacturing – Helps in handling molten glass and ceramic materials without contamination.
