摘要：

Thick films of Bi-Sr-Ca-Cu-O were deposited on (100) MgO substrates by screen-printing technique with the starting composition 1112. To attain the superconducting state, the films were subjected to two-step heat-treatment. R-T and XRD have been studied for films annealed at different durations of the second step. Initially T(c) (R = 0) increased from 77 to 103 K as the annealing duration was increased after which T(c) decreased. Kinetics of the growth of high T(c) phase is discussed in the light of our results.
