Degradation of sinterability and superconducting properties of fine particle YBa sub 2 Cu sub 3 O sub 7 sub - sub y by exposure to moisture

Reaction with moisture at RT proceeds rapidly for < or = 48 h, then slows. The sinterability and superconducting properties (magnetic flux exclusion) of the powder also degrade rapidly, but slow. Suggestions for minimizing the presence of moisture includes processing the oxide in a nonaqueous sol...

Zusammenfassung:Reaction with moisture at RT proceeds rapidly for < or = 48 h, then slows. The sinterability and superconducting properties (magnetic flux exclusion) of the powder also degrade rapidly, but slow. Suggestions for minimizing the presence of moisture includes processing the oxide in a nonaqueous solvent.
