Title:
SUPERCONDUCTIVE MATERIAL
Document Type and Number:
WIPO Patent Application WO2003015187
Kind Code:
A3
Abstract:
Oxidic superconductive material can be processed into bodies that have an extremely high critical current density in the presence of external magnetic fields with a strength of up to 5 Tesla, if the material is characterised by a lithium cation, magnesium cation or nickel cation concentration. Preferred materials are YB-CO materials and bismuth oxide-based superconductor material, (type "2212" or "2223" superconductor material).
