Pyrolytic Boron Nitride PBN Products
Product Overview
Pyrolytic 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) react 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 compound crystals such as germanium(Ge), gallium arsenide(GaAs), and indium phosphate(InP) owing to its intrinsic purity, superior mechanical properties, and physicochemical stability. PBN can withstand at 1800°C in vacuum and 2000°C in nitrogen, introducing it as a good choice for furnace components and melting vessels.
LEC crucible is a high-purity pyrolytic boron nitride crucible used in the Liquid Encapsulated Czochralski process to grow compound semiconductor crystals like GaAs and InP.
