Pyrolytic Boron Nitride (PBN) Boat Description
Pyrolytic Boron Nitride (PBN) Boats are highly specialized containers known for their exceptional thermal and chemical properties. PBN is synthesized through chemical vapor deposition, resulting in a material with excellent thermal conductivity and high-temperature stability, capable of withstanding temperatures up to 2000°C in inert atmospheres. PBN is chemically inert, resistant to most acids and alkalis, and does not react with molten metals, making it ideal for use in high-purity environments. Additionally, it exhibits outstanding electrical insulation properties and low outgassing, ensuring minimal contamination in sensitive processes. These characteristics make PBN boats particularly suitable for use in crystal growth, semiconductor manufacturing, and high-temperature material processing applications.
