High-T bscco tapes/wires

特許 権利維持 BSCCO was the first HTS material to be used for making practical superconducting wires. All HTS have an extremely short coherence length, of the order of 1.6 nm. This means that the grains in a polycrystalline wire must be extremely good contact – they must be atomically smooth. Further, because the superconductivity resides substantially only in the copper-oxygen planes the grains must be crystallographically aligned.
