ROLE OF SILVER ON PHASE-FORMATION AND TEXTURE DEVELOPMENT IN AG BSCCOCOMPOSITES/

Phase formation and texture development of BSCCO grains were investiga ted in Ag/BSCCO/MgO/Ag composites. Ag/BSCCO/MgO/Ag composites were fab ricated using the powder-in-powder method. It was observed that the BS CCO powder was almost fully converted into the 2223 phase at the Ag/BS CCO interface whereas partially at the MgO/BSCCO interface. Strong tex ture with the c-axis of the 2212 and 2223 phases normal to the tape su rface was developed at the interfaces of Ag/BSCCO and MgO/BSCCO. It wa s considered that the formation of the 2223 phase is closely related w ith the interaction between silver and BSCCO core. The results of this research seem to suggest that silver did not play a significant role in texture development of BSCCO grains.
