Zusammenfassung:In a method for forming joints between MgB2 filaments of superconducting wires, the MgB2 filaments from the wires to be joined are exposed, and the exposed filaments are then exposed to a mixture of magnesium powder and boron powder in a furnace, and the MgB2 filaments and the magnesium and boron powders are pressed together in the furnace. The MgB2 filaments and the magnesium and the boron powders in the furnace are heated, and oxygen that is present within the furnace is preferentially trapped, and thus removed from the joint, by providing titanium within the furnace.
