Oxidation behavior of spark plasma sintered (SPS) magnesium aluminum oxynitride (MgAlON) with different composition was investigated in present work. Results showed that the variation in composition had not obvious effect on the density of MgAlON, but had some effect on excess weight change. Also found that the oxidation behavior of MgAlON was different with oxidation temperature, which was attributed to the transformation from γ-Al2O3 to α-Al2O3. Moreover, the excess weight change was ascribed to the existence of lots of vacancies in γ-Al2O3 and magnesium aluminate spinel (MgAl2O4ss).
