Research output: Contribution to journalArticlepeer-review


The sessile drop technique was used to study the wettability behaviour of silver on sintered YBCO substrates. The temporal evolution of wetting angle at a temperature of 980 °C is reported. SEM/EDS analysis on both surface and section of YBCO/Ag samples was performed: silver collects in particles, filling substrate pores in a layer of 200 microns under the silver drop. In this superficial region silver also induces partial melting of YBCO at a temperature highly lower than usual. The nature of this phenomenon is explained.
