Abstract: Based on the disproportionation reaction, SiC particles were coated with Cu. AES technology was carried out to determine the influence of size-distribution on the phase homogeneity between SiC and Cu. Cu tends to deposit on the large particles rather than on the very fine coexisted particles in a wide size-distribution powders. Nano SiC particles can be coated readily with the narrow particle size- distribution, which leads to the desired phase homogeneity.

Key words: coating, phase homogeneity, size-distribution, disproportionation reaction
