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 CN_x, which remained as an impurity phase in the final product.
