Abstract
We have synthesized Si3N4/SiC nanocomposites using a commercial polymer. Formation behavior of SiC nanoparticles has been studied using X-ray photoelectron spectroscopy (XPS). Based on the XPS results, we concluded that SiC nanoparticles were formed by a chemical reaction of Si provided from Si3N4 with free carbon obtained by pyrolysis of a polymer around 1300 °C. The presence of CNx compounds in samples processed in an Ar atmosphere supported our explanation.
