Summary Procedures for synthesizing high-T c YBa2Cu3O7−x superconductors, alternative to the standard ones, are here studied by four-contact resistance measurementsvs. temperature and by X-ray diffraction. While X-ray spectra are consistent with the known ones, small changes in the transition temperatureT c and in shape of the resistancevs. temperature curve in the transition zone are observed. These changes could be explained in terms of volume fraction occupied by superconductive grains rather than as due to the different adopted procedures of preparation.
