The Sr-substituted NdBa_1.5Sr_0.3Cu₃O_7-δ superconductor was prepared using the sol-gel derived, highly oxidized Ba_1.5Sr_0.5Cu₃O_5+x precursor. An orthorhombic NdBa_1.5Sr_0.5Cu₃O_6.9 was obtained by the reaction between Nd₂O₃ and Ba_1.5Sr_0.5Cu₃O_5.6 at 900°C under N₂ atmosphere. The superconducting transition temperatures of the sample, T_c(χ) = 85 K, T_c(onset) = 90 K and T_c(end) = 84 K, were slightly higher than the reported values. The formation pass through this preparation method, the "BCO route", and the effects of Sr substitution on the superconducting properties were discussed.
