  • Composite for making superconducting wires or tapes
    Patent number: 5200392
    Abstract: An improved ceramic-plus-metal superconducting composition of YBa.sub.2 Cu.sub.3 O.sub.6+x plus substantially pure aluminum for ultimate use in making superconducting devices such as wires and tapes for utilization in motors, generators, electric circuits, etc.
    Type: Grant
    Filed: October 18, 1990
    Date of Patent: April 6, 1993
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: A. Srinivasa Rao, Om P. Arora
  • Method to produce YBa.sub.2 Cu.sub.3 O.sub.6+x superconducting wires or tapes
    Patent number: 5063201
    Abstract: 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.

    Date of Patent: November 5, 1991
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: A. Srinivasa Rao, Om P. Arora
  • Method of producing YBa.sub.2 Cu.sub.3 O.sub.6+x superconductors with high transition temperatures
    Patent number: 4983571
    Abstract: A method for improving the superconducting transition temperature of the MBa.sub.2 Cu.sub.3 O.sub.x where M is selected from the group consisting of Y, Er, Eu, Yb, Dy and Ho and where x is a value of from 6 to 7 ceramic by utilizing specific sequences of heat treating times and temperatures in conjunction with the use of silver oxide in making superconducting devices or wires for ultimate use in motors, generators and electrical circuits.
