Ceramic matrix composite - Wikipedia

Silicon carbide. Pure silicon carbide is one of the most corrosion-resistant materials. Only strong bases, oxygen above about 800 °C, and molten metals react with it to form carbides and silicides. The reaction with oxygen forms SiO 2 and CO 2, whereby a surface layer of SiO 2 slows down subsequent oxidation (passive oxidation).
