摘要
用固态反应法制备不含稀土元类的BiSrCaCu_2Oy陶瓷高温超导体。该系统可能存在多个高温超导相,不同工艺可改变各超导相成份;150K附近可能有一更高温超导相。
The ceramic superconductors of Bi-Sr-Ca-Cu-O system were prepared by general ceramic manufacture. It is possible that there exists a 150K superconducting phase in the system. It is also shown that this system has serial superconducting phases which can be obtained by different methods.
