Description
Pyrolytic boron nitride is a grade of hexagonal boron nitride. It is produced by chemical vapor deposition to create its solid body, and all the boron nitride crystals grow parallel to the surface of which the vapor is deposited. Due to the nature of the CVD process, PBN parts generally are requested with a wall thickness not more than 3mm. PBN is also a good choice for extremely high purity of boron nitride. 99.99% is the typical grade. The CVD process gives this pyrolytic boron nitride almost perfect layered structure, which leads to anisotropic thermal conductivity, making it an ideal material to make crucibles for crystal growing.
