| Zusammenfassung: | A method for forming joints between MgB2 filaments of superconductive wires comprises the steps of exposing MgB2 filaments from the wires to be joined; exposing the MgB2 filaments to a mixture of magnesium powder and boron powder in a furnace; and pressing the MgB2 filaments and the magnesium and boron powders together at a temperature in excess of or of order 540°C. Titanium is provided within the furnace and preferentially traps oxygen present within the furnace, preventing the formation of magnesium oxide. The titanium may in the form of pellets, and the furnace may be evacuated by a vacuum pump. |
