摘要
The oxidation kinetics of polymer-derived SiAlCN ceramics are determined at 1400 °C by measuring oxide-scale thickness as a function of oxidation time. The results reveal that the SiAlCN ceramics possess much better oxidation resistance than polymer-derived SiCN without Al, pure SiC and Si3N4. X-ray diffraction studies reveal that the oxide scales consist of cristobalite, plus a small amount of mullite for the sample with high aluminum-content. The reason that the SiAlCNs exhibited better oxidation resistance is discussed.
