Boron nitride tube is mainly used as insulating sleeves. Boron Nitride (BN), Hexagonal boron nitride (H-BN), and hot-pressed boron nitride are good self-lubricate ceramics that will withstand heat and maintain their lubricating capability during a high vacuum environment. Hexagonal boron nitride (H-BN) behaves almost like graphite mechanically, but it offers better electric resistance. The Boron Nitride Tubes (BN Tubes) from Heeger Materials are made up of hot-pressed boron nitride blank.
Hot pressed at high temperature (1900℃).
