Abstract

A new group of nanostructured composites with chromium silicide and silicon carbide has been developed. These composite powders which are about 20-40 rm in size were prepared by the chemical synthesis route and were characterized by UV, DTA/TGA, XRD, FTIR and SEM. Chemical reaction and phase formation versus the processing temperatures have been investigated and discussed. The particle size and the lattice parameter of the synthesized composite have been found to be dependent on the processing temperatures. A possible reaction mechanism of the nanostructured silicon oxide to silicon carbide is proposed.
