Abstract

The thermal conditions for the preparation of GdBa2Cu3O6.5+δ ceramics from mixed oxides and carbonates have been investigated. XRD, SEM, and TEM studies together with resistivity data show a good correlation among the sintering temperature, the lattice parameters and Tc and the resistivity values. The better properties obtained upon sintering at 930°-940° C fit a correlation between the barium shift, the ordering of the oxygen ions as expected by the rhombicity values and the Tc.
