Abstract
Low level doping (less than or equal to 1 atomic %) of Ag in Bi2Sr2CaC u2O8+d was performed via freeze-drying of nitrate solutions. Effects o f Ag doping on the c-axis lattice parameter, oxygen content and critic al temperature were monitored. Powder-in-tube tapes were fabricated us ing both Ag-doped and undoped Bi2Sr2CaCu2O8+d powders. Tapes were proc essed using a partial melt heat treatment in flowing oxygen. The effec ts of Ag doping on the critical current and microstructure were invest igated, specifically the Ag-Bi2Sr2CaCu2O8+d interface region.
