Sintered oxide superconducting wires

摘要

The present invention relates to a ceramics sintered wire. Ceramics materials, such as AlN, Si3N4 and Al2O3, have various kinds of superior characteristic including the heat-resistance and sintered ceramics materials have been watched with interest as superconducting materials having high critical temperatures. However, various kinds of disadvantage have been pointed out for the formation of the sintered ceramics materials in the form of thin wire and the practical use thereof. The present invention eliminates such disadvantages to provide a thin and long ceramics sintered wire having a sufficient strength and toughness to an extent of avoiding the breakage.
