Method for manufacturing a superconductive connection of MgB2 superconductor wires via a MgB2 matrix made of a Mg-infiltrated boron powder press body

摘要

a method for superconducting connection of two or more wires (1, 2), each of which at least one filament (3a - 3d) in which mgb2 or containing a mixture of mg and b containswith the superconducting connection exposed endbereiche (4a) of the filaments (3a - 3d) on a mgb2 matrix is characterized by the fact that(a) a pulverschu00fcttung (4) of boron powder is provided, in which the exposed endbereiche (4a) of the filaments (3a to 3d) of the wires (1, 2) hineinragen, while the boron of the boron powder, the pulverschu00fcttung (4) in amorphous modification.(b) the pulverschu00fcttung (4) with the hineinragenden, exposed endbereiche (4a) of the filaments (3a, 3b) to an extruded elements (8) is compressed.(c) and the extruded elements (8) from the surface (13) of the pressku00f6rpers (8) of a magnesium melt (10) infiltrated. with the erfindungsgemu00e4u00dfen procedure, the quality, especially the stromtragfu00e4higkeit and critical necessary, a superconducting connection of mgb2 - supraleiterdru00e4hten are improved.
