Superconducting wire, method of manufacture thereof and the articles derived therefrom

A method for making a superconducting wire comprising:

• contacting a boron filament, tape or a combination of a filament and a tape with molten magnesium to form a magnesium diboride wire.

A method for making a wire comprising:

• contacting a first end of a first superconducting wire with a second end of a second superconducting wire, wherein the superconducting wire comprises a superconducting filament having a superconducting composition comprising magnesium diboride;
• heating the first end of the first superconducting wire with the second end of the second superconducting wire at a point to form a joint, wherein the superconducting filament having the superconducting composition is in continuous electrical contact with any other part of the superconducting filament after the formation of the joint.
