Subramanian et al. found superconductivity at 80 K in Tl_(0.5)Pb_(0.5)Sr_2CaCu_2O_y sample with YBa_2 Cu_3 O_(7-δ)-like structure. However, there is unstable factor in the structure of the superconductor. Total plus valence is 12.5, and total minus valence is 14. The structure was further stabilized by partial substitution of Y, La, Nd orPr for Ca and Sn~(4+) or Sb~(5+) for (Tl, Pb), so that T_c was achieved above 100 K. For example, T_c is about 103 K in a sample with nominal composition (Tl_(0.4) Pb_(0.5)Sn_(0.2))Sr_2(Ca_(0.8)Y_(0.2))Cu_2O_(7-δ). During the preparation of superconductors, the temperature of samples was very slowly down after sintering, or samples were annealed at 500—700 ℃. The samples absorbed the oxygen during cooling, but no phase change occured. Appropriate amount of the oxygen made T_e higher.
