<p>A method for the manufacture of a superconductor in the form of a single-filament or multi-filament wire or tape is described at least one core material of one or more non-superconducting, powered intermetallic compounds of at least one element from group VB and at least one element from group IIIA and/or IVA of the periodic system being placed in an outer tube of an element or alloy thereof from group VB of the periodic system, which outer tube is placed in a matrix of conducting material and is subjected to a heat reaction treatment in a manner such that a coherent layer with superconducting properties is produced. Subsequently at least one thin-walled inner tube of a material, which does not adversely affect the superconduction, is used, whereby at least said intermetallic compound, which is brought in compact form, is included in said inner tube, and whereby finally said inner tube and said intermetallic compound are included as a whole in the outer tube. Said intermetallic compound can be mixed with a powdered lubricant or combination of lubricants containing preferably an element from said group IIIA and/or IVA and none of these lubricants affecting the superconduction adversely. A superconductor thus manufactured is indicated.</p> |
