Growth of Flower-Like AIN by Combustion Synthesis Assisted with Mechanical Activation
Flower-like AlN microstructure with many cone-like petals was prepared by combustion synthesis assisted with a mechanical activation (MA) method using NH4Cl as a reacting additive. The products were characterized by X-ray powder diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), energy dispersive spectrum (EDS) and transmission electron microscopy (TEM). A possible mechanism for the growth of AlN microflowers was proposed base on several parallel experiments and discussion. It was found that both the MA time and NH4Cl content play crucial roles for the growth of the flower-like microstructure.
