Abstract
The utility model discloses a superconductive wire rod belonging to the field of superconductive wire rod manufacturing technique, which is characterized by comprising MgB2 superconductive core wires. The outside of the MgB2 superconductive core wires is sequentially provided with a metal Nb barrier layer and a coalesced copper stabilization layer. The thickness of the metal Nb barrier layer is 1 to 2 mm. The thickness of the coalesced copper stabilization layer is 1.5 to 2.5 mm. The diameter of the superconductive wire rod is 12 to 18 mm. According to the technical scheme of the utility model, due to the adoption of the metal Nb material, Mg, B or phase-forming MgB2 is prevented from reacting with the coalesced copper stabilization layer. Meanwhile, the metal Nb material is also prevented from reacting chemically with the above powders. In this way, the metal Nb material is served as the ideal material for preparing the barrier layer of the MgB2 superconductive wire rod. The superconductive wire rod is simple and reasonable in structure, excellent in thermal stability and low in manufacturing cost. Meanwhile, the superconductive wire rod has certain strength and bending degree.
