PBN is a grade of hexagonal boron nitride. It is made by a chemical vapor deposition process to create its robust body, and all the boron nitride crystals grow parallel to the surface on which the vapor is deposited. Due to the nature of the CVD process, the PBN products generally request the product; thick wall products are not more than 3mm. PBN is also the right choice for extremely high purity boron nitride. As the purity of gas material (BCl3 + NH3 –> BN +HCl) is a lot higher than regular boron nitride powder, purity for PBN is quite high, and 99.99% is the average grade. With its high purity, high mechanical strength, high performance with molten metal, and salts, PBN are becoming a widely used material in high vacuum processes. Without showing melting point and high thermal conductivity, pyrolytic content is ideal to be used as a vacuum furnace part. The CVD process gives this PBN an almost perfect layered structure, which leads to anisotropic thermal conductivity, making it an ideal material to make crucibles for crystal growing. Molecular beam epitaxy (MBE) is a standard process for gallium GaAs crystal production, and PBN is the ideal material to make MBE crucibles. INNOVACERA® Performance Pyrolytic boron nitride properties are as below: Good thermal conductivity High insulation resistance High dielectric strength over wide temperature ranges Extremely pure Non-wetting Non-toxic Non-reactive to most other compounds Withstand high temperatures and rapid cooling
