Superconducting Properties of Y-Ba-Cu-O Sheet by a Tape Casting Method
YBa2CuO3O7-δ (YBCO) superconducting sheets were successfully fabricated by a tape casting method. Critical temperature (Tczero) was 92.IK with a tape sintered at 940°C for 10 hours in oxygen. The (001) planes of YBCO particles were oriented parallel to the casting plane of the 9 green sheet. The highest Jc was 1,510A/cm2 at 77K in zero magnetic field. It is supposed that the grain orientation contributed principally to the enhancement of Jc of the YBCO sheet.
