Abstract
On the base of the Tl-system high Tc superconductor[1–2] a new Tl-Tc-Ba-Ca-Cu-O system, which has good mechanical and electromagnetic properties and fine chemical stability, has been developed by doping with microamount of technetium (Tc) in the exploration of increasing superconductive transition temperature.
Project sponsored by the National Natural Science Foundation of China.
