Boron Nitride Gasket is formed of boron nitride (BN) — a compound with equal numbers of boron and nitrogen atoms. Heeger Materials provides our customers with high-quality hexagonal boron nitride ceramic gaskets, washers, and seals (BN ceramic) at a competitive price.

The hexagonal form (HBN) like 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 features a high hardness which is inferior only to diamond. The rare wurtzite BN (WBN) modification is analogous to lonsdaleite, and it's going to even be harder than CBN. BN gaskets and BN seals are available from high-temperature-(1900C)-formed 99% pure composite boron nitride materials.
Hot pressed at high temperature (1900℃).
