Description of Boron Nitride Tube
Boron Nitride, also known as BN, Hexagonal boron nitride (H-BN), and hot-pressed boron nitride, is a good self-lubricate ceramic that can withstand high temperature and maintain its lubricating capability in a high vacuum environment. Hexagonal boron nitride (H-BN) behaves similar to graphite mechanically, but it offers better electrical resistance. The Boron Nitride Tubes (BN Tubes) from Stanford Advanced Materials (SAM) are made from hot-pressed boron nitride blank.

Applications of Boron Nitride Tube
The Boron Nitride Tube (BN Tube) from Stanford Advanced Materials (SAM) can withstand high temperatures in the high vacuum environment, and it also has excellent corrosion resistance and electrical resistance. Thus, Boron Nitride Tube (BN Tube) has a wide range of applications, such as:
Electric insulators in vacuum system
Boron Nitride components for PVD, MOCVD, MBE system
Nozzles for nonferrous metals metallurgy industry
Spacers for glass melting
Insulators for high-temperature furnace
Packaging of SAM Boron Nitride Tube
SAM’s Boron Nitride tubes are clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.
