摘　　要：The Ag/Bi Sr Ca Cu O (BSCCO) interfaces of silver sheathed Bi 2223 superconducting tapes were studied by using transmission electron microscopy (TEM). Most of the interfaces are even and well bonded. The (001) planes of 2223 phase are parallel to the interfaces. Some step like interfaces were observed. There is occasionally a layer of one half unit cell of 2201 phase at the interface. No orientation relationship between the superconductor and the silver exists in the tapes.The Ag/Bi Sr Ca Cu O (BSCCO) interfaces of silver sheathed Bi 2223 superconducting tapes were studied by using transmission electron microscopy (TEM).
