Description
Accelerated water and moisture degradation of YBa2Cu3O7(YBCO)-silver nonrandom composites is studied. Oxygen evolution for these composites immersed in water at 65 degree C was compared with that for regular YBCO ceramic material prepared under similar sintering conditions. Time evolution of the decay of crystalline structure was followed by x-ray diffraction for the composite material and for the regular YBCO ceramic. We find that the nonrandom Ag-YBCO composite exhibits high chemical and structural stability in the presence of water; this advantageous property is probably due to the encapsulation of the YBCO grains with silver in this composite material
