| Abstract: | Abstract: Two kinds of Ag sheathed multi fiber Bi HT c superconducting tapes (M27 and M19) were fabricated by PIT method. Both two tapes were made into electron microscope samples (planar view and cross section) and the microstructure was studied with H9000 TEM, JEM 2000FX TEM and JSM 840 SEM. Phases of BSCCO superconduction tapes mainly consisted of 2223 phase. A few 2212 phase intergrown with 2223 phase were observed. |
