The effects of sintering time on the orthorhombic structure and positron lifetime parameter in YBa 2Cu 3O 7-δ have been studied by XRD?SEM and the positron experiments. It is found that on the condition of 950℃/12-72h
the positron experiment has good stability and reliability. This experiment indicates that the longer sintering time is needed to prepare Y-123 samples.
