Abstract
- Abstract: High purity quasi-octahedral polycrystalline explosion phase boron nitride (e-BN) submicron-powders were synthesized in an autoclave at 600°C for 6h using Mg, FeB1.3 and NH4Cl as the raw materials. Samples were characterized by SEM, FSEM, EDX, TEM, HRTEM, SAED, X-ray powder diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. The as-synthesized e-BN powders demonstrated a face-centered cubic structure with lattice parameter of 8.300Å. Besides the e-BN samples presented a quasi-octahedral morphology with an average diameter of 0.8μm. The effects of time, temperature, raw materials and possible catalytic reaction mechanism of the growth of quasi-octahedral polycrystalline e-BN were also discussed. [Copyright &y& Elsevier]
