PBN Pyrolytic Boron Nitride Disc Ring

PBN Pyrolytic Boron Nitride Disc Ring

Pyrolytic boron nitride (PBN) disc rings are specialized components made from pyrolytic boron nitride, a synthetic ceramic material with exceptional thermal, mechanical, and electrical properties. PBN has an extremely low coefficient of thermal expansion, similar to that of silicon, which ensures minimal thermal stress and distortion when subjected to temperature fluctuations.


1. Laboratory Furnaces: PBN disc rings are employed in high-temperature laboratory furnaces and ovens for research and materials testing.

2. Molecular Beam Epitaxy (MBE): In MBE systems, PBN disc rings are used as crucibles or substrates for the growth of thin films due to their high-purity and low-contamination properties.

3. Nuclear Fusion: In experimental nuclear fusion research, PBN is used in certain diagnostic and plasma-facing components.

4. Aerospace: PBN is used in aerospace applications, such as rocket nozzles and components, where it can withstand extreme temperatures and provide electrical insulation.

5. Ion Implantation: In ion implantation equipment used in the semiconductor industry, PBN is utilized as an insulating material in the ion source.

6. High-Temperature Crucibles: PBN disc rings can serve as crucibles for high-temperature processes like crystal growth, sublimation, and purification of materials.

7. Semiconductor Manufacturing: PBN disc rings are used in semiconductor processing equipment, particularly in high-temperature applications, where they provide excellent thermal stability and electrical insulation.

8. Optical Coating Equipment: PBN components are used in high-temperature, vacuum-based coating systems due to their excellent thermal and electrical properties.
