Abstract

AlN nanopowders are successfully synthesized via electrical Al wire explosion in liquid nitrogen. After pickling in 15 % HCl-ethanel, the purified AlN nanopowders are characterized by various techniques. It is observed that the synthesized AlN nanoparticles are hexagonal AlN (h-AlN) exhibiting various shapes, including sphere, spheroidicity, polygon and hexagon. The results show that the charging voltage affects on the AlN content and the morphology of samples, significantly. Further more, it is observed that synthesized AlN particles in the size of 100-300 nm are coated by an amorphous layer mostly resulted from the high cooling rate in liquid nitrogen.
