Boron nitride (BN) can form compounds with either sp3-hybridized or sp2-hybridized bonds. The most studied sp3-hybridized phase is cubic (c-BN), but there is also a wurtzite phase (w-BN) that is an analogue to the III−nitrides AlN, GaN, and InN. The sp2-hybridized BN (sp2-BN) can crystallize into two different phases: hexagonal (h-BN) and rhombohedral (r-BN). These two phases can be regarded as two different stacking sequences of the same basal plane, where h-BN and r-BN have a lattice parameter along the c-axis of 6.656 Å and 10.000 Å, respectively.
