摘要:Abstract(#br)Fabrication processes for increasing the critical current density J c in BiSrCaCuO superconductor have been studied. Calcining mixtures of raw material in a reduced oxygen partial pressure or in vacuum after in-air calcination is found to be effective. Intermedi...

摘要:Abstract(#br)Silver-clad tapes of high T c Bi-Pb-Sr-Ca-Cu-O superconductors have been fabricated through the powder-in-tube method. The critical current density, J c , of a thick tape was 534 A.cm −2 (77 K, 0 T). Subsequent rolling and sintering of the tapes led to a gradual...
