Ag-sheathed Bi-2223 mono-and multifilamentary superconducting tapes have been obtained from wires produced by the powder-in-tube method. The tapes have been characterized by scanning electron and polarized optical microscopy, together with critical current density (Jc and Jc(B)) measurements. A syst

✦ Synopsis
Continuous 2212 Bi-Sr-Ca-Cu-O / Ag superconducting composite tapes were prepared by a novel technique called Current Heat Melt-Painting (CriMP) method. The composite tapes exhibit excellent flexibility, and no microcrack can be found even at 2-3 mm curvature radius. The superconducting layer is very dense and very even in thickness and binds very well with Ag substrate observed by SEM.
