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 (1,470 °F), 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).
Silicon Carbide Patents and Patent Appliions (Class 148
Abstract: A method is disclosed for forming crystalline silicon carbide (SiC) semiconductors on a semiconductor-on-insulator (SOI) structure. In this method, the thin silicon layer of an SOI substrate is converted to silicon carbide using a carbonization reaction. The SiC layer is then, optionally, further increased in thickness using a vapor deposition reaction, preferably using a silicon

Silicon Carbide Discovered to be a Key to Developing
Silicon carbide, which is incredibly hard and heat-resistant, is the key behind optoelectronics. Electroluminescence was first seen in silicon carbide. The material was used in the 1920s for the first LEDs. Silicon carbide LEDs were mass produced in the 1970s. But after that, direct-bandgap semiconductors took over silicon carbide’s role.
