Hexagonal Boron Nitride ( h-BN) | SpringerLink

Abstract. Boron nitride (BN) exists in three crystalline forms. The hexagonal form (h-BN) is the normal phase stable at room temperature and pressure [1].It is isostructural with graphite. At high temperature and pressure, h-BN (space group=P6 3 /mmc) may transform into a wurtzite structure (P6 3 mc).
