Extended abstract Aluminium oxynitride (AlON) is a single phase stable solid solution of Al 2 O 3 and AlN. It has attracted much attention because of its superior optical, mechanical and dielectric properties. These favorable properties make AlON important in infrared and visible window applications as well as transparent armor applications [1, 2]. Several methods have been used to synthesize AlON including simultaneous reduction and nitridation of Al 2 O 3 [3], gel-nitridation of aluminum
