The effect of annealing duration in oxygen flow on the superconducting characteristics of YBa{sub 2}Cu{sub 3}O{sub {approximately}7} bulk ceramics was investigated by structural, electrical, magnetic, and electronic microscopy investigations. The long-time annealing is deleterious for the superconductivity in YBa{sub 2}Cu{sub 3}O{sub {approximately}7} ceramics. The optimum time interval for annealing is from 20 to 70 h at 950{degrees}C, and within this range the maximum value of T{sub c} is obtained.
