BN0948 disc produced from pyrolytic boron nitride (PBN)

Pyrolytic Boron Nitride (PBN) Disc Description

Pyrolytic Boron Nitride (PBN) is synthesised by a CVD process using BCl₃ and NH₃ at high temperature and low pressure. PBN products have a purity of 99.99 % or higher and are very stable in vacuum or under an inert atmosphere. They exhibit anisotropic thermal conductivity, thereby making them a suitable material for the manufacture of components for furnaces and vacuum systems.

Applications of Pyrolytic Boron Nitride (PBN) Discs

Pyrolytic Boron Nitride (PBN) is used in the semiconductor industry and in vacuum systems.

Our PBN discs are employed in various industries and research domains:

• Semiconductor Fabrication: PBN discs are utilised during semiconductor wafer processing to maintain precise temperature control during deposition, etching and annealing processes.

• Aerospace and Defence: The thermal stability and electrical insulation properties of PBN render it a suitable choice for components in aerospace, for example, rocket nozzles where high temperatures occur.

• Scientific Research: Researchers utilise PBN discs for experiments in high-temperature environments, covering material testing, plasma physics and crystal growth.

• Optoelectronics: Due to its thermal conductivity, PBN is used for the mounting of laser diodes and as a substrate for high-power laser devices.

• Solar Cell Manufacture: PBN discs are employed as substrates for the deposition of thin-film solar cell materials and facilitate efficient heat dissipation.

Characteristics of Pyrolytic Boron Nitride (PBN) Discs:

High Thermal Conductivity: PBN exhibits high thermal conductivity. This property permits its use in managing and dissipating heat during high-temperature operations.

High Temperature Stability: With a melting point above 3000°C (5432°F), PBN remains stable and preserves its structural integrity under high temperatures. Consequently, it is applied in processes with substantial heat exposure and rapid temperature changes.

Chemical Inertness: The inherent resistance of PBN to chemical reactions and corrosive substances, including acids and alkalis, ensures sustained performance in aggressive environments.

Low Outgassing: PBN exhibits low outgassing. This characteristic is important for applications in vacuum and cleanroom environments where contamination is a concern.

Electrical Insulation: PBN functions as an effective electrical insulator. It is therefore used in semiconductor and electronics applications that require electrical isolation.
