摘要：

Surface modifications from exposure of YBa2Cu3O7-delta pellets and thin films of the 1:2:3 composition to ambient atmosphere and 85% relative humidity at 50-degrees-C were measured using x-ray photoelectron spectroscopy and scanning Auger electron multiprobe. Surface formation of BaCO3 and Ba(OH)2 was detected. The surface layer of the sintered pellets did not have any Cu after 48 h of moisture treatment. The degradation in the thin-film samples was substantially less. The rate of degradation appears to be controlled by grain-boundary diffusion.
