Method of producing YBa2Cu3O6+x superconductors with high transition temperatures

摘要

A method for improving the superconducting transition temperature of the MBa2Cu3Ox 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.
