Resumo

The high Tc superconducting (HTS) materials are now applied in electric power systems. Cables, trans-formers and motors with superconducting tapes are now in test worldwide. However, HTS materials have intrinsic anisotropy that affects the values of their critical currents. Textured HTS samples present improved superconducting properties. The present work describes a study of the texturing process in monofilamentary tapes, using as HTS material the BSCCO system, i.e., 1G HTS tapes (Bi2212/Ag). The purpose of this work is presentation the alternative method for feature in the characterization of texturing in the superconductor ceramics Bi2212 tapes.
