Chemically Stable Boron Nitride Ceramic BN Tube

Chemically Stable Boron Nitride Ceramic BN 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. 


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
