Boron nitride was able in baggy (a-BN) and apparent forms. The a lot of abiding clear anatomy is hexagonal one, aswell referred to as h-BN, α-BN or r-BN (graphitic BN). Hexagonal boron nitride (point accumulation = D6h; amplitude accumulation = P63 / MMC) has a bandage anatomy agnate to graphite.
The cubic clear anatomy has a sphalerite anatomy and alleged diamond, as able-bodied as beta-BN or C-BN. Wurtz BN anatomy (W-Bonpoint accumulation = C6v; amplitude accumulation = P63mc) has the aforementioned anatomy as the Lonsdaleit, attenuate hexagonal carbon polymorphs. Both c-BN and w-BN, boron and nitrogen atoms in the tetrahedra are grouped, but the angles amid adjoining tetrahedra analyze amid them.
