A sol-gel method was applied to preparation of the NdBa₂Cu₃O_7-δ superconducting ceramics. Influence of synthesizing processes and heating conditions of gels on magnetic and electrical properties of NdBa₂Cu₃O_7-δ was investigated. It has been found that samples consisting of a single phase of NdBa₂Cu₃O_7-δ are obtained by reheating baked gels at 700°C under vacuum, which temperature is lower than those used till now for producing the NdBa₂Cu₃O_7-δ ceramics. It has also been confirmed that undergoing the incongruent melting is effective to improve the superconducting properties. T_c(onset) was reached 93K, and J_c of 1.47 × 106 A/cm² was obtained.
