Preparation of Bi-Sr-Ca-Cu-O superconductors from oxide-glass precursors
Patent
·
OSTI ID:868367
- Lemont, IL
A superconductor and precursor therefor from oxide mixtures of Ca, Sr, Bi and Cu. Glass precursors quenched to elevated temperatures result in glass free of crystalline precipitates having enhanced mechanical properties. Superconductors are formed from the glass precursors by heating in the presence of oxygen to a temperature below the melting point of the glass.
