Summary Two procedures of partial melting of bulk NdBa2Cu3O7−δ, in air and in reduced oxygen pressure, were developed. When the treatment was carried out in air, poor superconducting properties were observed. On the contrary, when the treatment was carried inP O 2=1.3 mbar, good properties were obtained, withT conset=93 K and 100% shielding at lower temperatures. Near full density (2.5×2.5×28) mm3 Nd1.07Ba1.89Cu3.04O7−δ bars, with domains extending in the mm size range, were obtained.
