000168066 5203_ $$aBi2Sr2Co1.8Ox bulk polycrystalline ceramics were prepared by conventional sintering of powders, obtained by polymer solution method and by directional growth using the laser floating zone technique. Microstructural analysis showed randomly oriented grains in the classical sintered materials, while in the laser-textured samples well oriented crystals with the c-axis nearly perpendicular to the growth direction were observed. A significant reduction on electrical resistivity, compared with the sintered materials, was observed due to the decrease on the secondary phases content. As a consequence, a raise on the power factor of about 2 and 5 times, compared with the classically sintered samples, was obtained for the as-grown and annealed laser-textured samples, respectively. The maximum power factor obtained at 650 °C in the annealed laser-textured samples (∼0.20 mW/K2 m) is much higher than the best value obtained in sinter–forged textured materials at the same temperature.
