| Abstract | Abstract Bi 2− x Pb x Sr 2 CaCu 2 O y textured materials ( x = 0.0, 0.2, 0.4, and 0.6) have been successfully prepared by the laser floating zone technique. Microstructure and electrical properties ( J C and T C ) have been clearly affected by Pb addition. From the E – I curves, slope of the transition between the superconducting and the normal state ( n ) at 77 K reaches a maximum of about 16 for the 0.4 Pb doped samples. This value is much higher than the typical ones for the Bi-2212 materials. Moreover, when the electrical properties of the 0.4 Pb doped samples are measured at lower temperatures (between 65 and 77 K), n values increase when the temperature is decreased. A maximum n value of 32 has been reached at 65 K which makes this material very attractive for its use as resistive fault current limiters. |
