Pyrolytic Boron Nitride (PBN) Disc Description
Pyrolytic Boron Nitride (PBN) Disc is synthesized on the mold by CVD process, with BCl3 and NH3 at high temperature and low pressure. PBN products are extremely pure (99.99% or even higher) and very stable in a vacuum or inert atmosphere. They feature anisotropic thermal conductivity, making them an ideal material to make components for furnace & vacuum systems.
