Silicoaluminum Carbonitride With Anomalously High Resistance To Oxidation And Hot Corrosion

Due to their excellent thermal and mechanical properties silicon-based ceramics and composites are prime candidates for high temperature structural applications. In this communication the authors report for the first time that amorphous silicoaluminum carbonitride (SiAlCN) ceramics possess anomalously high resistance to oxidation and hot-corrosion. A mechanism underlying the observed phenomena is discussed
