Boron Nitride Evaporation Boats: Ideal Ceramic Components for High-Temperature Vacuum Applications
The boron nitride evaporation boat (BN evaporation boat) is a high-temperature device made of high-purity hexagonal boron nitride ceramics . It is usually in a boat shape or custom-made, and can hold various evaporation materials. During use, it not only serves as a container for holding molten materials but also maintains the cleanliness and stability of the working environment. Unlike ordinary ceramic components, the BN evaporation boat possesses both structural strength and chemical inertness, and can be used stably for a long time under extreme conditions. The comprehensive advantages of materials and techniques (1) Core material: High-purity hexagonal boron nitride High-purity h-BN serves as the first line of defense to ensure process cleanliness. Its purity is ensured not to have any impurities precipitate at high temperatures, fundamentally eliminating the pollution caused by the vessel, maintaining extremely high purity of the evaporated materi...
