Pyrolytic Boron Nitride (PBN) at Information Materials

Free standing pyrolytic boron nitride (PBN) is fabricated by the well-known chemical vapor deposition process in which the ammonia gas (NH3) and a gaseous boron halide such as boron trichloride (BCl3) 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 components, and also free-standing crucibles for fabrication of single and binary 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.

Due to its high structural stability, Acids, alkalis, organic solvents, molten metals, and graphite do not react with PBN. 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.
