Boron nitride - Wikipedia
Boron nitride is a thermally and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN.It exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice. The hexagonal form corresponding to graphite is the most stable and soft among BN polymorphs, and is therefore used as a lubricant and an additive to cosmetic products.
