- Abstract:
-
Industrially produced SiC submicron powder was selected to prepare nanoCu by displacement reaction. SiC/Cu coated powder was prepared by direct reduction-rotation precipitation process. Cermet composites are obtained by atmosphere sintering. The original SiC powder, coated composite powder and firing samples were characterized by AES, XRD, SEM and other analytical methods. The results show that the coated composite powder has a "core-shell" structure, and Cu2O appears in the composite powder due to the spontaneous oxidation of Cu. SiC particles in the wrapped structure inhibit the grain growth of Cu during the sintering process, so that the sintered sample presents a nanostructure.
