Abstract: Nanonsized AlN powders were prepared by nitridation of coarse aluminium powder in flowing N₂ and NH₃ gases, using NH₄Cl and KCl as additives. XRD analysis indicated that the pure phase of AlN powder could be obtained by nitridation at 1000˚C for 4 h with NH₃ gas. The average particle size of the AlN powder estimated from the XRD pattern is about 29 nm. FE-SEM micrograph revealed the spherical morphology of the powder particles whose sizes are in the range of 26-43 nm.
