| 中文摘要 | The effect of processing conditions on phase formation, solid solution range and superconductivity for die La1+zBa2-zCu3Oy system was investigated systematically again to obtain and understand the optimum preparation condition of La-123 superconductors. The results indicate that (1) the solid solution ranges are z=0.20-0.70 and z=0 for La1+zBa2-zCu3Oy sintered and cooled in air and in N-2, respectively. (2) In LaBa2Cu3Oy, La can substitute for Ba, but Ba cannot substitute for La. This substitution is suppressed when LaBa2Cu3Oy was sintered and cooled in N-2. (3) A single phase LaBa2Cu3Oy superconductor with the highest T-c of 97 K was obtained for the first time when the sample is sintered at 900 degrees C for 40 h in N2 and cooled down to 305 degrees C in N-2 then treated in dried flowing O-2 for 40-60 h.
