Pyrolytic Boron Nitride (PBN) Tubes Description
Pyrolytic Boron Nitride Tubes are 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 it an ideal material to make components for furnace & vacuum system.
