Abstract: Nano SiC particles in diameter of about 100nm were commercially available, Cu particles were precipitated during
the disproportionation reaction process. The morphology of the mixed powders containing the nano SiC and Cu particles were observed by SEM or Auger
microprobe, in which the spherical particles dominated. EDS and AES were carried out to determine the element distribution in the local area and spot
across a single particle. The coating process of Cu on the surface of the nano SiC particles ensures the homogeneous phase-distribution between the two
different phases.

Key words: nano SiC, Cu, dispersion, disproportionation
