Abstract
An electric resistance heating element is formed by a molybdenum disilicide wire loop formed by separate lengths of the wire having ends positioned together and butt welded to the end of a molybdenum disilicide connecting wire of larger diameter than that of the lengths. The lengths diverge from each other so they are electrically separated. Electrical connections with the free ends of the separate lengths of wire can provide for electrically powering the loop.
