Abstract
We have synthesized Si3N4/SiC nanocomposites using a commercial polymer. The formed Si3N4/SiC nanocomposites have been studied using Raman scattering and X-ray photoelectron spectroscopy (XPS). The Raman scattering measurements showed that the formation of SiC started at 1200°C and that the main phase was 3C-SiC. The XPS results suggested that the SiC nanoparticles were formed by a chemical reaction of Si provided from Si3N4 with free carbon obtained by pyrolysis of polymer. The XPS results also indicated that residual carbon reacted with N2 to form CNx, which remained as an impurity phase in the final product.
