In this study we synthesized the YBa2Cu3O7-δ superconductor using the unconventional method of plasma sintering in the range of abnormal glow discharge (AGD). The samples were treated with different sintering temperatures and times. As reference we used a superconductor sample obtained by using the conventional method (resistive furnace). The structural characterization of these samples was performed by X-ray diffraction measurements and Rietveld refinements. Superconductivity behavior was determined by analyzing magnetization curves as a function of the temperature according to zero field cooling (ZFC) and field cooling (FC) experimental procedures. The samples sintered by AGD presented structural characteristics (orthorhombic Pmmm) and superconductivity with a critical temperature of Tc ~ 92 K, which were similar to those obtained by the conventional method, but with a significant reduction of temperature and time under proper pressure environment during the sintering process. © 2017.
