抄録

Bi-2212/Ag tape samples with finely dispersed oxide(x-Al₂O₃ or MgO) particles were prepared by the partial melt-solidification technique. The formation and superconducting properties of the tape samples have been studied in relation to microstructure. In case of a-Al₂O₃ particles addition, as the oxide additive content increased, the Ic value at 77K and OT decreased remarkably because of reaction between a-Al₂O₃ and 2212 phase. On the other hand, MgO particles were uniformly dispersed in the Bi-2212 matrix without any reaction between 2212 phase and MgO, so that Ic almost unchanged. Isothermal magnetic hysteresis loop of MgO added samples was larger than that of non-added samples. These results suggested that MgO particle addition was effective for improvement in the flux pinning properties of the Bi-2212 phase.
