## Description

- description: Superconducting joints between Bi-2223 tapes were fabricated by a hot-pressing
    process with a 24 h heat treatment. We developed specialized equipment to apply
    pressure to the joint during the heat treatment. Hot pressing is effective for
    producing practical critical current even by the short heat treatment. The superconducting
    joint in a closed-loop showed a resistance of 7.3 × 10 −15 Ω at 4.2 K in self-field.
    The maximum persistent current that could flow in the loop was estimated to be
    about 170 A at 4.2 K. The purification and further densification of the intermediate
    layer in the superconducting joint are issues that need to be addressed. Once
    these issues are addressed, the hot-pressing process should be a promising method
    for fabricating high-performance Bi-2223 superconducting joints in high yields
    within a short processing time.
