To reduce the production cost of Bi-2223 superconducting tapes, Bi-2223/Ag/Ni tapes were fabricated by the powder-in-tube process. The effect of heat treatment on the microstructure and critical current of the Bi-2223...
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) ...
