In a method for forming joints between MgB 2 filaments of superconducting wires, the MgB 2 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 MgB 2 filaments and the magnesium and boron powders are pressed together in the furnace. The MgB 2 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. |
