Abstract
A method for the production of a superconducting polycrystalline wire rod having all the crystal (a, b, c) axes thereof aligned is disclosed, which consists of a step of arraying a plurality of superconducting whiskers of a composition of Bi.sub.2 Sr.sub.2 CaCu.sub.2 O.sub.8 (Bi-2212 phase) in such a manner as to parallellize the fiber axes of the whiskers and then aligning all the crystal axes of the superconducting whiskers with parallellized fiber axes and a step of heat-treating the resultant whiskers.
