Two or more superconductors are reacted together to form a non-superconducting phase encapsulating a residual superconducting phase. For example YBa2Cu3 oxide is reacted with Bi2Sr2CaCu2 oxide to form a superconducting product containing a novel non-superconducting oxide of Y, Bi, and Ba. A superconducting YBa2Cu3 oxide remains as an interconnected phase throughout the product. The new non-superconducting phase largely encapsulates and insulates the superconducting phase. |
