Title:
PRODUCTION OF OXIDE SUPERCONDUCTOR
Document Type and Number:
Japanese Patent JPH01133906
Kind Code:
A
Abstract:
PURPOSE:To obtain an oxide superconductor having a high critical temp. with high reproducibility by treating precursors of the constituent elements of an oxide superconductor in an oxygen atmosphere and subjecting the resulting oxide superconductor to reduction treatment in a hydrogen atmosphere. CONSTITUTION:Precursors of the constituent elements of an oxide superconductor are treated in an oxygen atmosphere and the resulting oxide superconductor is subjected to reduction treatment in a hydrogen atmosphere. Since the amt. of oxygen in the oxide superconductor can be made smaller by reduction, the concn. of oxygen is controlled to the optimum value to increase the critical temp.
