The efforts of carrying forward superconducting materials to commercialization can be overcome by with high performance potentiated a suitable processing technique. In this work, extreme critical currents up 241 A @ 77 K were attained tuning the crystal growth in directional solidification process. Bulk rods textured Bi-2212/2.9 wt % Ag obtained changing conventional laser floating zone technique through application d.c. electrical current during crystallization Using an optimized...
Textured rods of Bi-2212 based materials with nominal compositions Bi2Sr2CaCu2O8+δ, Bi2Sr2CaCu2O8+δ+1 wt% Ag, Bi1.6Pb0.4Sr2CaCu2O8+δ, and Bi1.6Pb0.4Sr2CaCu2O8+δ+3 Ag were fabricated using a laser floating zone (LFZ) melting method. The electrical, magnetic, mechanical properties the resulting after annealing characterized. Pb doping results in decrease transport critical current density, Jc,t (from 4.4 × 107 to 6 106 A m−2 at 65 K self-field) as well worsening properties, by about 35%...
Laser floating zone processing methods are particularly suitable for studying crystal growth and the development of texture from melt in many materials used n electrooptics, example. A system is descrbed that allows different laser wavelengths to be used, first results on BSCCO superconducting fibers processed using lasers presented. The Figure compares textures produced Nd:YAG CO 2 magnified image .
