Process for increasing the pinning force of superconducting Bi-Sr-Ca-Cu-O ceramic moldings |
摘要 |
Process for increasing the pinning force of superconducting Bi-Sr-Ca-Cu-O ceramic moldings, which comprises heating the pure-phase 2212 phase of a Bi-Sr-Ca-Cu-O ceramic molding under pure oxygen or an oxygen-containing gas for from 1 to 40 minutes to a temperature of from 825 DEG to 900 DEG C. and generating secondary-phase precipitates in the process.
