Product Overview

Boron Nitride Ceramics are high-performance materials made using advanced international technologies to ensure high purity and superior high-temperature resistance. Manufactured through cold isostatic pressing and biaxial pressure hot-press sintering, these ceramics have a high density, ensuring long-term stability and excellent thermal properties. The absence of binders during the manufacturing process guarantees the stability and durability of the material, making it ideal for use in high-temperature, high-pressure, and electrical insulation applications.

Features

  • High Purity: Produced from high-temperature boron nitride materials to ensure purity.
  • High Density: Manufactured using advanced cold isostatic pressing and biaxial hot-press sintering technology to enhance material density and lifespan.
  • Excellent High-Temperature Resistance: Capable of working stably in extreme temperatures, ideal for various high-temperature applications.
  • Binder-Free Production: No binders are used in production, ensuring material stability and durability.

Applications

  • Molten Metals: Used for high-purity boron nitride crucibles in high-temperature molten metal environments.
  • Ceramic Sintering: Used for sintering boron nitride, silicon nitride, aluminum nitride, and other ceramic and powder materials in crucibles and sintering plates.
  • High-Temperature Furnaces: Employed in high-temperature furnaces as electrode insulation parts and protective tubes, offering superior electrical insulation and thermal stability.
  • Polysilicon Ingot Furnaces: Used in polysilicon ingot furnaces for boron nitride insulation components to ensure stable operation in high-temperature environments.
