ABSTRACT:
A superconductive alloy of titanium and niobium is formed during reduction of niobium pentoxide by adding an effective quantity of titanium metal and/or titanium oxide to a reduction mixture of aluminum and niobium pentoxide. The resulting mixture is reacted to form the desired niobium titanium alloy below an aluminum oxide or aluminum oxide-titanium oxide slag. The slag is easily separated from the alloy.
