Boron Nitride Gasket Description

Boron Nitride Gasket is made of boron nitride (BN) — a chemical compound with equal numbers of boron and nitrogen atoms. The hexagonal form (HBN) corresponding to graphite is the softest and most stable form among BN polymorphs, and is therefore used as a lubricant and an additive to cosmetic products. The cubic (CBN) variety analogous to diamond has a high hardness which is inferior only to diamond. The rare wurtzite BN (WBN) modification is similar to lonsdaleite, and it may even be harder than CBN.

Boron Nitride Gasket Applications

– Boron Nitride components for PVD, MOCVD, MBE systems.
– Insulators for high-temperature furnace
– Feedthrough for high-voltage equipment
– Spacers for glass melting
– Boron Nitride parts for ion injection equipment
