Abstract

The effect of annealing duration in oxygen flow on the superconducting characteristics of YBa2Cu3O∼7 bulk ceramics was investigated by structural, electrical, magnetic, and electronic microscopy investigations. The long-time annealing is deleterious for the superconductivity in YBa2Cu3O∼7 ceramics. The optimum time interval for annealing is from 20 to 70 h at 950°C, and within this range the maximum value ofT c is obtained.
