A method for superconductingly connecting two or more wires (), each comprising at least one filament (-) that contains MgBor a mixture of Mg and B, wherein a superconducting connection is realized through exposed end regions () of the filaments (-) via an MgBmatrix, is characterized in that a bulk boron powder () is provided into which the exposed end regions () of the filaments (-) of the wires () project, the boron of the bulk boron powder () being present in amorphous modification. The bulk powder () is then compacted together with the projecting exposed end regions () of the filaments () to form a compressed element () and the compressed element () is infiltrated with molten magnesium () from the surface () of the compressed element (). The method improves the quality, in particular, the current-carrying capacity and the critical magnetic field strength of a superconducting connection of MgBsuperconducting wires.

A method for connecting two or more superconducting wires (), each comprising at least one filament (-) that contains MgB, wherein the superconducting connection is realized through exposed end regions () of the filaments (-) via a superconducting matrix, is characterized in that a bulk powder () of a high-temperature superconductor (HTS) powder with a transition temperature of T&#x3e;40K is provided, into which the exposed end regions () of the filaments (-) project, wherein the Boron of the Boron powder of the bulk powder () is in amorphous modification, and the bulk powder () is compacted together with the projecting exposed end regions () of the filaments (-) to form a compressed element (). The method improves the quality, in particular, the current carrying capacity and the critical magnetic field strength of a superconducting connection of two MgBwires.

A superconductive composite member, which has a core composed of an oxide ceramic material which is surrounded by an envelope, has an increased core density in order to achieve a higher critical current density. The increased core density is obtained during a hot-shaping step of the core material in the envelope, wherein the composite is heated to a temperature wherein the superconductor material is present in either a molten or a partially molten state.
