| Abstract: | The preparation conditions of the high TC ceramic superconductor Ba(Pb,Bi)O3 is correlated with the superconducting transition. Transition onsets of all materials are similar, but transition widths and transition completeness is strongly dependent on firing temperature. Only materials prepared over a narrow temperature range, resulting in a nearly ideal weight loss, have a complete and narrow transition. |
