Boron Nitride Nozzle (BN Nozzle) Description
Boron Nitride (BN), also known as hexagonal boron nitride (H-BN) and hot-pressed boron nitride, is a good self-lubricate ceramic that can withstand high temperature ( >3000℃ in an inert atmosphere) and maintain its lubricating capability in a high vacuum environment.
Boron Nitride Nozzle (BN Nozzle) is made from hot-pressed boron nitride blank. Hexagonal boron nitride (H-BN) behaves similarly to graphite mechanically but offers excellent electrical resistance. Boron Nitride Nozzle (BN Nozzle) has very low wettability with metal. Compared with graphite, it is a better choice for high-temperature metal spray.
