概要

• 論文の詳細を見る

• High T_c superconductor Tl_2Ca_2Ba_2Cu_3O_x were prepared by a two-stage process: prequenched after a 880℃ × 12 minutes heat treatment, and then annealed at 880-890℃ for 120 minutes in a flowing oxygen atmosphere. The zero-resistivity temperatures distribute in a range from 115 to 119 K. The X-ray diffraction patterns exhibit that they are all in the 2223 phase. The results indicate that the predominance of Tl_2Ca_2Ba_2Cu_3O_x phase is irrelevant to whether the composition of the starting material is TlCa_3BaCu_3O_x or Tl_2Ca_2Ba_2Cu_3O_x by using our process. The influence of each stage in our process has also been studied.
