## Samples with the nominal composition BizSrzCa,\_,Na,CuzO, (with x=0.05,0.2,0.4 and 0.5) were prepared by the solid state reaction method. The role of Na and the effect of various heat treatments in the 2212 composition were studied. From the X-ray diffraction data it is found that the samples a

Recent results in a systematic study of the stability of supercurrents in Bi-2212 tapes with randomly oriented, highly splayed columnar defects are presented as a function of defect density. The defects were artificially created by fission fragments of bismuth nuclei, fissioned by irradiation with e
We have succeeded in studying the structural characteristics of a single thread of Bi-based 22 12-phase whisker by X-ray diffraction. It is found that the structural characteristics of a single thread of whisker coincide with those of a 2212-phase single crystal. The single thread of whisker is a 22
An inductive shielded core fault current limiter model using a commercially available melt cast processed Bi-2212 tube was realized and tested. The device was designed with a nominal power rate of 0.5 kVA. Static tests were initially performed to determine the non-linear Z(I) characteristic of the l
