The amazing toughness of Hexagonal Boron Nitride uncovered

The chemical formula h-BN stands for hexagonal boron nitride, a chemically and thermally resistant refractory compound of boron and nitrogen. It appears in a variety of crystalline forms that are isoelectronic to a carbon lattice with a comparable structure. Among the BN polymorphs, the hexagonal form equivalent to graphite is the most solid and soft […]
