Abstract
The effect of annealing duration in oxygen flow on the superconducting characteristics of YBa2Cu3Osimilar to 7 bulk ceramics was investigate d by structural, electrical, magnetic, and electronic microscopy inves tigations. The long-time annealing is deleterious for the superconduct ivity in YBa2Cu3Osimilar to 7 ceramics. The optimum time interval for annealing is from 20 to 70 h at 950 degrees C, and within this range t he maximum value of T-c is obtained.
