A sol-gel method was applied to preparation of the NdBa2Cu3O7-δ superconducting ceramics. Influence of synthesizing processes and heating conditions of gels on magnetic and electrical properties of NdBa2Cu3O7-δ was investigated. It has been found that samples consisting of a single phase of NdBa2Cu3O7-δ are obtained by reheating baked gels at 700°C under vacuum, which temperature is lower than those used till now for producing the NdBa2Cu3O7-δ ceramics. It has also been confirmed that undergoing the incongruent melting is effective to improve the superconducting properties. Tc(onset) was reached 93K, and Jc of 1.47 × 106 A/cm2 was obtained.
