A single superconducting phase in the Yttrium-Barium-Copper Oxide system of overall composition Y1Ba2Cu3O9-x can be fabricated in bulk form. This phase has low contact resistance, relatively low resistance, and is completely superconducting below 90oK with an onset above 90oK and possibly as high as 96oK.
