Fabrication and electrical properties of ceramic superconductor/polymer composites

Abstract
Superconductor/polymer composites were prepared by mixing powders representing the Y‐Ba‐Cu‐O and Bi(Pb)‐Sr‐Ca‐Cu‐O systems with high‐density polyethylene. Their electrical resistivities were measured as a function of temperature. By controlling the powder preparation techniques, it was possible to fabricate composites with superconductive transition to zero resistivity in the Bi(Pb)‐Sr‐Ca‐Cu‐O system. These composites can be fabricated in certain desired shapes.
