Abstract

Abstract: Nanocrystalline boron nitride (BN) was prepared by the reaction of BBr3 and Mg3N2 at 400 °C. X-ray powder diffraction (XRD) patterns can be indexed as hexagonal BN with the lattice constants of a=2.504 and c=6.671 Å. The transmission electron microscopy (TEM) images showed whisker-like and flake-like morphology. The product was also characterized by X-ray photoelectron spectrum (XPS) and Fourier transformation infrared spectroscopy (FTIR). [Copyright &y& Elsevier]
