Abstract

The quality of superconducting silver clad (Bi,Pb)-2223-tapes essentially depends on the applied precursor powder. The choice of the processing parameters of the precursor preparation (calcination procedure) is decisive for the current carrying capability of tapes. The properties of 2212 and the occurence of secondary phases in precursors can be regulated by partial oxygen pressure, temperature, and time in the calcination annealing. Precursors containing orthorhombic (Bi,Pb)-2212 with high T_c without Pb⁴⁺-phases yield high critical currents
