Abstract
Abstract A method of manufacturing a superconductor consisting of different materials by introducing into material of an element or an alloy at least one element of another group or a compound, whereupon the diameter of the assembly, if desired, is reduced and subsequently a superconductive layer of said elements is formed by thermal treatment.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
135 words
A method of manufacturing a superconductor consisting of different materials which comprises introducing into a first component selected from the elements or alloys of the elements of Group VB of the Periodic Table, a second component containing an accelerator and consisting essentially of an element selected from the Group consisting of Group IIIA and Group IVA of the Periodic Table, or a second component containing an accelerator and consisting essentially of a mixture of (1) a compound or alloy of a Group VB element with an element selected from the Group consisting of Group IIIA and Group IVA of the Periodic Table with (2) an element selected from the Group consisting of Group IIIA and Group IVA of the Periodic Table, and thermally treating said materials to produce a superconductor having a superconductive boundary layer.
Claim 2
Independent Claim
135 words
A method of manufacturing a superconductor consisting of different materials which comprises introducing into a first component selected from the elements or alloys of the elements of Group VB of the Periodic Table, a second component containing an accelerator and consisting essentially of an element selected from the Group consisting of Group IIIA and Group IVA of the Periodic Table, or a second component containing an accelerator and consisting essentially of a mixture of (1) a compound or alloy of a Group VB element with an element selected from the Group consisting of Group IIIA and Group IVA of the Periodic Table with (2) an element selected from the Group consisting of Group IIIA and Group IVA of the Periodic Table, and thermally treating said materials to produce a superconductor having a superconductive boundary layer.
Claim 3
Dependent Claim
16 words

Claim 4
Dependent Claim
14 words
The method of claim 1, wherein the second component is in a compact state.
Claim 5
Dependent Claim
32 words
The method of claim 1, wherein at least one of the elements or compounds has the form of a powder and at least one of the elements is in a compact state.
Claim 6
Dependent Claim
17 words
The method of claim 1, wherein the first component is vanadium and the second component is gallium.
Claim 7
Dependent Claim
26 words
