Pyrolytic Boron Nitride (PBN) is defined as a high-temperature, anisotropic ceramic, a combination of high electrical resistance and superior thermal conductivity. This non-toxic, non-porous compound is exceptionally pure due to the synthesis process which is a high-temperature or low-pressure chemical vapor deposition.
Pyrolytic boron nitride can be deposited conveniently or machined into a wide range of components for various applications in manufacturing items such as cubicles, boats, bottles, tubes, sheets, coatings or graphite, machined plate products, etc. PBN’s directional thermal conductivity can provide an excellent heat spreading capability to maintain a uniform temperature. Properties of PBN such as good thermal conductivity, high strength, and low coefficient of thermal expansion render the material resistant to thermal shocks. PBN possesses several exceptional properties such as high purity, low density, non-porous structure, and high dielectric strength which differentiate it from the other substitutes available. Performance PBN possess properties such as intrinsic purity, thermal stability, and superior mechanical strength which make it an ideal choice for high-temperature furnace and electrical components, microwave and semiconductor components, and industry standardized crucibles for production of gallium arsenide crystal (GAN).
PBN-coated graphite heating elements provide uniform temperature profiles for the manufacturing of compound and silicon semiconductors. It also possesses specific properties such as inertness to acids, alkalis, organic solvents, molten metals, or graphite. Bulk impurity it withstands a temperature of 1800°C in vacuum and 2000°C in nitrogen, showing no melting point, making it an excellent choice for furnace components and melting vessels.
