Bi-pb-Sr-Ca-Cu-O bulk samples with nominal composition of Bil.6Pb0.4Sr2Ca3Cu4Oy (2234) were prepared by a melt casung method. The melting process was carried out on two different powders; one consisting of the precursor materials, and one in which the precursor had been calci,r,d.Th~-~ffects of the

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
The critical current density at 77 K at 0 T and the tensile strength at room temperature of high Tc Bi(Pb)-Sr-Ca-Cu-O and Y-Ba-Cu-O oxides in silver-sheathed tapes prepared by the powder-in-tube method were investigated. The main results can be summarized as follows. (1) The critical current density
