The single-phase Υ-AlON powders were synthesized from three different precursors: Υ-Al2O3+C, Al(OH)3+C, NH4Al(OH)2CO3+C at 1750°C by carbothermal reduction and nitridation . The effects of aluminium source and synthetic process conditions on the characteristic of Υ-AlON powders were investigated in order to optimize the preparation method. It was revealed that the wet chemical processing was helpful to reduce partical size. The median particle sizes (d50) of AlON powders synthesized from different precusors were 15.33 μm, 2.886 μm, 405.6 nm, respectively.
