摘要：

Tl-Ba-Ca-Cu-O ceramics were fabricated under various firing conditions at a nominal composition of Tl1Ba1Ca3Cu3Oy. When the ceramics were fired at 760°C for periods longer than 240 h, Tc over 125 K was obtained from Meissner measurements. The volume fraction of the superconducting phase at 125.0 K was estimated to be approximately 10%. This synthetic condition could yield the sample showing Meissner effect over 125 K with good reproducibility. © 1990.
