摘要：

The lead-containing, nearly single-phase 2212 material of nominal composition Bi1.75Pb0.25Sr2CaCu2O8+z has a T(c) of about 70 K after air quenching. By controlling post-treatment, the transition temperature can be raised to about 98 K. Since no significant changes in the oxygen content are observed, we conclude that the function of post-treatment is to produce a more favorable ordering of oxygen in the lattice. Accordingly, all dimensions are influenced by the post-treatment. Additional results for air-quenched 2212 material with variations in the Bi:Pb:Sr:Ca ratio show that differences in the position of T(c) are also reflected in variations of the cell dimension, thus pointing to an extended field of existence for the 2212 phase in the system Bi-Pb-Sr-Ca-Cu-O with phase boundaries which are still unknown.
