Various superconducting glass ceramics based on the Bi-Ca-Sr-Cu-O system with T c (onset)=80∼95 K and T c (zero)=63∼78 K were prepared by a melt-quenching method. The melt-quenched samples of Bi 1.5 CaSrCu 2 O x and Bi 1.5 Ca 1.5 SrCu 2 O x were found to be a glass with a glass transition of about 425°C; these samples became high- T c superconductors by annealing at 820°C.
