Boron Nitride - an overview ScienceDirect Topics

Boron nitride (BN), consisting of boron–nitrogen covalent bonds, was commonly used as a refractory material. Isoelectronic to sp 2 carbon lattice, BN was generally compared with carbon allotropes. The cubic form of BN (c-BN) has a diamond-like crystalline arrangement and the bulk crystal of h-BN is analogous to graphite crystal. 43 The 2-D sheets of h-BN are the most stable and soft among ...
