Boron Nitride Break Ring Description

Boron nitride, or BN, is 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 lubricant and an additive to cosmetic products. The cubic (CBN) variety analogous to diamond has 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.
