Abstract: The oxidation of β-Si_[6-z]AlzOzN_[8-z]s (z = 1, 2, and 3) prepared by a combination of combustion synthesis (CS) and spark plasma sintering (SPS) was investigated. The oxidation experiments were conducted at temperatures of 1000℃, 1200℃, and 1400℃ in air for 100 h (360 ks). Their oxidation kinetics follows a parabolic rate law, and the deviation from that increases with a decrease in the z value. The results of XRD and EPMA showed that the oxide formed on β-SiAlONs (z = 1 and 2) consists of silica and mullite, and on β-SiAlON (z = 3) of only mullite.
