摘要

Spherical core-shell Cu-Ag bimetallic powders with mean diameter about 50 nm were prepared by substitution reaction method. The powders had two kinds of structures: surface-decorating structure and full-package structure, determined by XRD and TG analysis. Also, their shapes and compositions were observed and examined respectively by TEM and XRF.
