摘要：

Superconductivity up to 105 K was observed in the Ca-free Tl-Pb-Sr-Pr-Cu-O system. Powder X-ray diffraction analyses showed that a 132 phase was responsible for the observed superconductivity. (Tl0.8Pb0.2)(Sr2.5Pr0.5)Cu2O(z) was nearly single 132 phase, and had a tetragonal unit cell with a = 3.84091 (38)-angstrom and c = 12.1952 (12)-angstrom.
