| Abstract: | The preparation technology of Tl-Ca-Ba-Cu-O supercoductors was investigated. The supercoductivity of zero resistance transition temperature at 125 K was obtained in the samples with nominal composition of Tl_5Ca_(3.8)Ba_(2.8)Cu_6O_xor TlCa_4Ba_3Cu_6O_x was obtained when the suitable sintering temperature, time and cooling rate was chosen. |
