A superconducting oxide is melted in an oxygen-rich environment, rapidly solidified and annealed in an oxygen atmosphere. The resulting material has a fine grain structure, is chemically homogeneous, and has enhanced resistance to environmental degradation. The materials have well-defined superconducting...http://www.google.fr/patents/US4937225?utm_source=gb-gplus-shareBrevet US4937225 - Rapid solidification processing of oxide superconductors
