Title:
METHOD FOR MANUFACTURING SUPERCONDUCTING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2012/067067
Kind Code:
A1
Abstract:
This method for manufacturing a superconducting material is characterized in that a superconducting crystal is precipitated by performing heat treatment in: (1) a state wherein a Bi-Sr-Cu-O amorphous material and a Ca compound are in contact with each other; or (2) a state wherein a Bi-Ca-Cu-O amorphous material and a Sr compound are in contact with each other; or (3) a state wherein a Bi-Sr-Cu-O amorphous material and a Bi-Ca-Cu-O amorphous material are in contact with each other.
