Bi2-x Pb (x) Sr2CaCu2O (y) (x = 0.0, 0.3, 0.4, and 0.5) textured materials have been prepared by the laser floating zone technique. The E - I curves showed and increase of the slope of the normal to superconducting transition with Pb addition. The best values have been obtained for the 0.4 Pb-doped samples, around 16 at 77 K. In spite of this improvement, Pb addition decreased J (C) and T (C) in all cases. On the other hand, electrical characterization at lower temperatures has led to an impressive raise in the 0.4 Pb-doped samples, reaching n values around 31, and J (C) of about 3,000 A/cm (2), at 65 K. At the same time, the mechanical integrity of the vitreous precursor materials has been determined. All the obtained results clearly indicate that these precursors, when properly processed by the laser floating technique, are promising candidates for practical applications as current limiters.
