Oxidation behavior of spark plasma sintered (SPS) magnesium aluminum oxynitride (MgAlON) was investigated in this study. Monophase MgAlON without pores was easily obtained and evaporation was sufficiently limited by the utilization of the SPS process. The MgAlON powder was oxidized above 750℃, and a detectable mass gain of the MgAlON plate could not be obtained below 1200℃, because the oxidation reaction was of a very low level and occurred only on the surface. High temperature were favorable to oxidation reaction. According to the isothermal mass gain and evolution of oxidized morphology of the plates oxidized at different temperature, it could be deduced that the oxidation of MgAlON was limited by interface reaction. To analyze more profoundly, an oxidation model was proposed.
