Abstract

Interaction Ag with 2223phase BSCCO superconductor. The addition o/Ag20 (0, 2.5, 5, and 10 wt% Ag) to matrix of2223 phase BSCCO superconductor that sintered at 845 oCfor 72 hours in air havebeen investigated. The Ag additions promote thedecomposition of2223phasesto 2212phasesBSCCO andcaused present some impurities phases. The impurities areproducted bythe Agaddition ableto be usedas effectively pinningsources to hold vortex (fluxline) movement. The Tcmeasurement results are 111 K, 107 K, 105 K, and103Kwith addition ofO, 2.5, 5, and10 wt% Ag respectively. The Jc measurement results are 3.6 xl (f, 5.6 x1 (f, 6.9 x1 (f, and U. 8xl (fAm'2 with addition ofO, 2.5, 5, and 10 wt% Ag respectively. From theXRD analysis shown that the addititon ofAg caused peaks of 2212phases BSCCO are clearly visible and the samples contain some impurities phases (CuO, Ca^ CuO^, dan CajPbOJ. From the SEM analysis shown that the addititon ofAg should lead to a slight increase of the plate like grain size of 2223phase BSCCO with increasing Ag content. From this experiment we conclude that the Tc depress and the Jc enhance with increasing Agcontent. The addititon ofAg should leadto a slight increase ofthe platelike grain size of 2223 phase BSCCO with increasing Ag content.
