Abstract
This disclosure discloses a method of making a niobium alloy having the general formula Nb.sub.y M where M is aluminum, gallium, indium, tin, germanium, silicon, or a mixture thereof. A niobium halide having the formula NbX.sub.y is reactive with M in a solution of a liquid alkali metal, where X is halogen and y is the valence of niobium. Also disclosed are spherical particles of the superconducting niobium alloy which are made by this method and a wire and magnet made from these particles.
