The properties of hexagonal boron nitride are generally different from those of graphite

What is boron nitride?Boron nitride (chemical formula BN), a synthetically produced crystalline compound of boron and nitrogen, is an industrial ceramic material of limited but important application, principally in electrical insulators and cutting tools. It is made in two crystallographic forms, hexagonal boron nitride (H-BN) and cubic boron nitride (C-BN). H-BN is prepared by several methods, including heating boric oxide (B2O3) with ammonia (NH3). It is a platy powder consisting, at the molec
