Multifilamentary Nb3Sn composite conductors with 65 880 and 421 160 filaments have been fabricated in long lengths by the internal tin-diffusion method. Filament diameters are in the range from 31.1 nm to 274 nm. Conductors were heat treated for 1 to 53 days at various temperatures from 400ยฐC to 700

The determination of the critical current density (Jc) of a superconducting ceramic is a vital part of the assessment of its suitability for electrical and electronic applications. However, in bulk materials where the current carrying capacity of a test specimen is typically several amps, great care
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
