Supraleitung und Tieftemperaturtechnik. Spezifische Materialentwicklung von schmelztexturierten YBCO Hochtemperatursupraleitern fuer den Einsatz in passiven magnetischen Lagern Abschlussbericht

The objective of the project was the development of a standardized processing technology for shaped materials made of melt-textured High-Temperature Superconductors (HTS) and to be utilized in passive magnetic bearings. Based on earlier internal R and D projects of Forschungszentrum Karlsruhe, the results were as follows: Despite significant impurities in the commercial powders, well-textured single domain samples of sizes up to 60 mm could be fabricated with good reproducibility by employing seed crystals. The resulting levitation forces should provide new opportunities for the economic use of these HTS materials in magnetic bearings as well as other electric power applications.
