摘要：
Two types of Bi-2212 thick films using Bi-2212 superconducting whiskers have been prepared. One is composite films incorporating the whiskers (20 wt.%). The composite films have been prepared by an isothermal partial melting method. It is found that the incorporation of the whiskers is effective for overcoming weak links at grain boundaries. In consequence, J(c) for the composite film is about three times higher than for a film without whiskers (monolithic film). The other is in-plane aligned Bi-2212 thick films consisting of only whiskers. The in-plane aligned films have been prepared by hot pressing the a-axis aligned whisker preforms. J(c) for the in-plane aligned film is two times higher than for the in-plane random thick film.
