We report the effect of silver addition on superconducting performance ofbulk YBCO (YBa2Cu3O7) superconductor. All the studied samples are prepared byconventional solid-state reaction method. Rietveld fitted X-ray diffractiondata confirmed the single phase formation for all the studied samples. DetailedAC susceptibility measurements as a function of driven AC amplitude (1Oe-17Oe)of these samples revealed the enhancement of grains coupling with increasing Agcontent in YBCO+Agx composite system. 10wt% Ag added YBCO superconductorsexhibited the optimum inter granular coupling. The Scanning Electron Microscopy(SEM) observations indicate an increase in the grains connectivity in terms ofnarrow grain boundaries for doped samples. The average grain size is found toincrease with Ag doping. It is concluded that limited addition of Ag in bulkYBCO superconductor significantly improves the grains coupling and as resultoptimum superconducting performance. YBCO+Ag composites could prove to bepotential candidates for bulk superconducting applications of the studied highTc system.
