LAMINATED SUPERCONDUCTING CERAMIC TAPE

摘要

A superconducting ceramic (10) includes a superconducting ceramic tape (12) joined to laminates (14, 16). The superconducting ceramic tape (12) may be joined to each laminate (14, 16) by solder (13, 15) or epoxy, or by solderless mechanical bonding techniques. The laminates (14, 16) and superconducting ceramic tape (12) are joined such that the tape (12) is under a compressive stress. The compressive stress is of a greater amount than the compressive stress which results from differences in thermal expansion of the tape and the laminate. The greater compressive stress can be achieved by putting the laminate under a greater tension than the superconducting ceramic tape during joining of the superconducting ceramic tape to the laminate. The superconducting ceramic may include only one laminate joined to the superconducting ceramic tape.
