摘要：

AlON powders of varied composition were produced from Al–Al2O3 mixtures by SHS without and with B/BN chemical furnace under high pressure of nitrogen gas as a third reactant and characterized by XRD, SEM/EDS, and chemical analysis. The products obtained without chemical furnace were found to contain Al5O6N, Al7O3N5, AlN, as well as unreacted Al and Al2O3. The powders produced by SHS with chemical furnace contained largely the Al5O6N phase with an admixture of Al7O3N5 and AlN. After etching with KOH solution, the Al5O6N powders became single-phased. The etching also leads to marked changes in the microstructure of synthesized powders. Due to their unique microstructure, the synthesized Al5O6N powders can be expected to exhibit unusual electrophysical and optical properties. © 2015, Allerton Press, Inc.
