  • Re-type oxide superconducting wire and process for producing the same
    Patent number: 8326387
    Abstract: A RE-type oxide superconducting wire having excellent angular dependence for magnetic field of Jc is obtained by finely dispersing magnetic flux pinning centers into a superconductor. A mixed solution which comprises a metal-organic complex solution including a metal element which composes a RE-type oxide superconductor whose Ba content is reduced and a metal-organic complex solution including at least one or more kinds of metals which are selected from Zr, Ce, Sn, or Ti which has a larger affinity for Ba is coated onto an intermediate layer of a composite substrate, and the assembly is then calcined to disperse artificially and finely oxide particles (magnetic flux pinning centers) including Zr. Thus, the angular dependence for magnetic field (Jc,min/Jc,max) of Jc can be remarkably improved.
