Why is Cubic Boron Nitride Called a Superhard Material?

by Stanford Advanced Materials | Dec 20 2018 Cubic boron nitride (CBN) is a super hard material synthesized by hexagonal boron nitride and catalyst under high temperature and pressure. The hardness of this superhard material is second only to diamond in industrial application.

Nanocomposite thin films also exhibit superhardness, and some of these materials have hardnesses approaching that of diamond Cubic boron nitride (c-BN), which Is naturally superhard, has proven very difficult to deposit at thicknesses exceeding 0.1 μm, but It is now reported that chemical vapor deposition techniques based on fluorine chemistries can produce c-BN films up to 20 μm thick.

boron nitride

Boron nitride

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.

Introduction and application of Boron nitride ceramics

Boron nitride hexagonal crystals are converted to cubic boron nitride crystals or boron nitride crystals at high temperature and pressure. Hexagonal boron nitride Hexagonal crystal boron nitride has a layered structure similar to graphite. Its appearance is white powder and its properties have many similarities, so it is also called "white
