Ternary molybdenum chalcogenide superconducting wire and manufacturing thereof

A process for manufacturing a ternary molybdenum chalcogenide (TMC) superconducting wire, the superconducting wire comprising a bulk material, other than SnMo6S8, PbMo6S8, or a mixture thereof, in which an engineering critical current density of the superconducting wire is uniform over a length and is at least 100 A/mm2 at magnetic fields above 22 Tesla, the process comprising:

• producing the superconducting wire by powder metallurgy;
• compressing a powder, comprising the bulk material other than SnMo6S8, PbMo6S8, or a mixture thereof, by hot isostatic pressing (HIP) to form a 100% dense bulk material;
• machining the 100% dense material into the shape of a cylinder;
• loading the cylinder of 100% dense material into a high purity molybdenum can;
• sealing the high purity molybdenum can under vacuum;
• loading the cylinder of 100% dense material in the high molybdenum can into a stainless steel can suited for applications at the temperature of liquid helium;
• sealing the stainless steel can under vacuum;
• thereafter reforming hot extrusion between 1,200° C. and a limit of the stainless steel;
• and
• performing hot wire drawing between 500° C. and 1.200° C. to allow plastic/superplastic deformation of one or more resulting ternary molybdenum chalcogenide filaments.
