Product Description
Pyrolytic boron nitride is a grade of hexagonal boron nitride. It is produced by chemical vapor deposition process to create its solid body and all the boron nitride crystals grow parallel to the surface of which the vapor is deposited on.
Due to the nature of CVD process, PBN parts generally are requested the wall thickness not more than 3 mm. PBN is also a good choice for extremely high purity of boron nitride. 99.99% is the typical grade. The CVD process give 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.
INNOVACERA PBN parts includes PBN Discs, PBN Sheets, PBN Filament Rings, PBN VGF Crucibles, PBN LEC Crucibles, PBN MBE Crucibles, PBN Conical Crucible and Other Custom PBN Parts.
