Abstract
A superconducting material useful for forming electrolytic devices is made by establishing multiple niobium or tantalum components in a primary billet of a ductile material; working the primary billet through a series of reduction steps to form the niobium or tantalum components into elongated elements; cutting and restacking the resulting elongated elements with a porous confining layer to form a secondary billet, working the secondary billet through a series of reduction steps including twisting and final rolling to thin ribbon cross-sections with greater than 5:1 Aspect Ratios; cutting the resulting elongated billet into sections; and leaching the core and sheath at least in part.
