Product Description Product DescriptionPyrolytic Boron Nitride (PBN) is fabricated by the well-known Chemical Vapor Deposition (CVD) process in which the ammonia gas (NH3) and a gaseous boron halide such as boron trichloride(BCI3) are reacting in a high temperature CVD furnace to deposit PBN on an appropriate substrate such as Pyrolytic Graphite.PBN is known as an excellent choice for high-temperature furnace and electrical components, semiconductor and microwave compounds crystals such as germanium(Ge), gallium arsenide(GaAs), and indium phosphate(InP) owing to its intrinsic purity, superior mechanical properties, and physico-chemical stability. PBN can withstand at 1800°C in vacuum and 2000°C in nitrigen, introducing it as a good choice for furnace components and melting vessels.
