Boron Nitride Gasket and seal are formed of boron nitride (BN) — a compound with equal numbers of boron and nitrogen atoms. Nextgen Advanced Materials provides our customers with high-quality hexagonal boron nitride ceramic gaskets, washers, and seals at a fast delivery time. Customization is available too.
As the professional manufacture, we would like to provide you Nextgen Boron Nitride Gasket and Seal. The company has always been oriented by customer demand and respect for talents, constantly improve their strength, improve service level and quality. Boron Nitride Gasket and Seal 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.
