  • Fluorination of superconducting YBa.sub.2 Cu.sub.3 O.sub.7-x powder
    Patent number: 5081103
    Abstract: A method of incorporating fluorine into the YBa.sub.2 Cu.sub.3 O.sub.7-x system by annealing YBa.sub.2 Cu.sub.3 O.sub.7-x powder in a fluorine-containing gas, especially NF.sub.2 gas. The YBa.sub.2 Cu.sub.3 O.sub.7-x material is annealed in the fluorine-containing gas (either pure NF.sub.3 or NF.sub.3 /O.sub.2 blend of F.sub.2 /N.sub.2 blend) at a temperature which allows sufficient reactivity with the fluorine gas while maintaining the system well below temperatures at which oxygen incorporation is observed to take place in the normal YBa.sub.2 Cu.sub.3 O.sub.7-x system.
