Synthesis and Characterization of Silver-Coated Copper Powder Layer

  This paper presents the process of preparing spherical silver-coated copper powder with a silver content of 30-50%,using chemical reduction and by adjusting the silver-coating process.By means of SEM,XRD,grain size analyser,digital ohmmeter and differential thermal analyser,the surface topology,structure and conductivity of silver-coated copper powder and raw copper powder are characterised.The results show that the spherical silver-coated copper powder has superior compact surface,complete coverage,a coated layer reaching a thickness of 336nm and excellent conductivity and anti-oxidation property.
