Abstract
The quality of superconducting silver clad (Bi,Pb)2223-tapes essentially de pends on the applied precursor powder. The choice of the processing paramet ers of the precursor preparation (calcination procedure) is decisive for th e current carrying capability of tapes. The properties of 2212 and the occu rence of secondary phases in precursors can be regulated by partial oxygen pressure, temperature, and time in the calcination annealing, Precursors co ntaining orthorbombic (Bi,Pb)-2212 with high T-c without Pb4+-phases yield high critical currents.
