Abstract
Official abstract text for this publication.
The present invention has as its problem the provision of a bulk oxide superconductor which has a high workability and high critical current density characteristic regardless of the external conditions and solves the problem by limiting the amount of addition of Ag to 5 mass % or less, using the QMG method to produce a bulk superconductor and thereby obtain a single crystal-like bulk superconductor of a structure with parts where Ag particles are present and parts where Ag particles are not present made to adjoin each other.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of production of a bulk oxide superconductor comprising heating a precursor of a bulk oxide superconductor to form a semimolten state and bringing a seed crystal into contact with it to obtain a single crystal-like REBa 2 Cu 3 O 7-x phase in which RE 2 BaCuO 5 phases are finely dispersed, said method of production of the bulk oxide superconductor comprising adding Ag: 0.5 to 4.6 mass % to said precursor of a bulk oxide superconductor and heating it to become a semimolten state, then bringing a seed crystal into contact with said semimolten state precursor and gradually cooling to make said precursor solidify into a single crystal shape. 2. The method of production of the bulk oxide superconductor according to claim 1 further comprising working said bulk oxide superconductor into a bar shape so that parts where Ag is present sandwich a part where Ag is not present.
