The thermal stability and high‐temperature strength of SiC filler/Si–C–N matrix particulate‐reinforced ceramic (PRC) composites were investigated. The PRC retained 115% of the room temperature strength at 1500°C in air because of the crack‐healing behavior. The thickness of SiO 2 formed on the PRC was 3 μm after an oxidation at 1500°C for 100 h in air. The strength of the PRC did not strongly decrease after the prolonged oxidation for 100 h. The SiC/Si–C–N PRC are a promising candidate for the applications at extremely high temperatures in air.
