초록정보

Superconducting Bi(Pb)-Sr-Ca-Cu-O powders were prepared by the emulsion drying method. The powders consisting of the low Tc phase $(Bi(Pb)_2Sr_2Ca_1Cu_2O_y)$ and small amount of $Ca_2PbO_4$ were prepared by calcining in low oxygen partial pressure at 750℃, 800℃, and 830℃. These calcined powders were used to prepare thick films on single crystal MgO(100) substrates using screen printing technique to study the effects of the calcination temperature on the high Tc phase $(Bi(Pb)_2Sr_2Ca_2Cu_3O_y)$ formation. The influence of normal sintering, step sintering, and partial melting process on the high Tc phase formation and superconducting properties were also studied. Different tendencies to form the high Tc phase depending on the calcination conditions and the sintering schedules were observed. The high Tc phase formed very quickly(sintering at 840℃ for 4h in the step sintering process), and the best films showed a sharp superconducting transition at about 105K. The highest value is 2,500A/㎠, whose sample is partially melted at 850℃/lh and slow cooled to 830℃ in the partial melting process.
