Pyrolytic Boron Nitride (PBN) Disc Applications

Pyrolytic Boron Nitride (PBN) Disc is used in semiconductor industries & vacuum systems.

Our PBN Disc finds application in various cutting-edge industries and research fields:

Pyrolytic Boron Nitride (PBN) Disc Features:

Outstanding Thermal Conductivity: PBN is renowned for its exceptional thermal conductivity, making it a preferred choice for heat management and dissipation in high-temperature environments. Its thermal conductivity is nearly on par with diamond, surpassing that of traditional ceramics.

High-Temperature Stability: With a melting point exceeding 3000°C (5432°F), PBN remains stable and maintains its structural integrity even under extreme heat, making it ideal for use in processes involving intense heat and rapid thermal cycling.

Chemical Inertness: PBN's inherent resistance to chemical reactions and corrosive substances, including acids and alkalis, ensures long-lasting performance and reliability in aggressive environments.

Low Outgassing: PBN exhibits minimal outgassing, a crucial characteristic for applications in vacuum and cleanroom environments, where contamination is a concern.

Electrical Insulation: PBN is an excellent electrical insulator, making it suitable for semiconductor and electronics applications where electrical isolation is essential.
