Method to produce YBa.sub.2 Cu.sub.3 O.sub.6+x superconducting wires or tapes

摘要

A method of making an improved YBa.sub.2 Cu.sub.3 O.sub.6+x ceramic superconductor. The method includes the steps of: adding aluminum powder to YBa.sub.2 Cu.sub.3 O.sub.6+x powder to form a powder mixture, pressing the powder mixture, and rolling the pressed mixture into a thin ceramic superconductor. The addition of aluminum results in improved superconducting transition temperature, ductility and formability.
