Preparation and characterization of coated nanoscale Cu/SiCp composite particles

Nanoscale Cu/SiCp composite particles were prepared using a coating method. XRD, AES, SEM, DSC-TG-MS techniques were used to characterize the coated composite particles. It was found that a core-shell structure is constructed in the coated Cu/SiC composite particles with the core of SiC and the shell of Cu. A new layer of Cu2O is created on the surface of the coated particles due to the oxidation of nano Cu crystallites. The expected sintering temperature for the coated Cu/SiC composite particles is below 950 °C.
