Description of Pyrolytic Boron Nitride Sheet

Compared with normal boron nitride ceramic, pyrolytic boron nitride (PBN) has raw materials with a much higher purity level. PBN sheets, discs, and other pyrolytic boron nitride products are synthesized on the mold by chemical vapor deposition (CVD) process, with BCl3 and NH3.

Pyrolytic boron nitride sheet exhibits high resistance to electricity but good thermal conductivity. It is a high-purity material with no porosity, which could be deposited on all kinds of graphite shapes by chemical vapor deposition (CVD). Although pyrolytic boron nitride could be deposited on various materials, it is usually used on graphite only, since the temperature of this CVD process is extremely high and the atmosphere is corrosive. PBN-coated graphite materials significantly enhanced the performance of the surface. Better purity, lower porosity, and roughness. PBN material could also stand high temperatures (2500 °C). As the coated products have great performance in high vacuum and high-temperature circumstances, they are ideal for applications in the semiconductor industry.

Applications of Pyrolytic Boron Nitride Sheet

• Semiconductor Manufacturing Equipment: PBN sheets are used as crucibles, boats, and other components in semiconductor manufacturing processes.
• Electronic Packaging: PBN sheets are used in electronic packaging to provide insulation and heat dissipation for high-performance semiconductor devices, including LEDs and laser diodes.
• Microwave and RF Amplifiers: PBN's high thermal conductivity and excellent dielectric properties make it an ideal material for use in microwave and RF amplifier applications.
• Crystal Growth Processes: PBN sheets serve as crucibles or containers in the growth of single crystals, such as gallium arsenide (GaAs) and other compound semiconductors.
• High-Temperature Furnaces: In high-temperature furnaces, PBN sheets can be used as insulators or as parts of the heating elements due to their ability to withstand high temperatures (up to approximately 2000°C in inert atmospheres) and their resistance to thermal shock.
• Neutron Radiation Shields: The boron in PBN has a high cross-section for absorbing neutrons, making PBN sheets useful as neutron radiation shields in nuclear reactors and research applications.
• Aerospace: The lightweight and high-temperature resistance of PBN make it suitable for various aerospace applications, including components that must withstand extreme conditions.
