Resumen: Bi2Ca 2Co 1.7Ox nominal composition ceramic rods were textured by the electrically assisted laser floating zone technique. A new composite formed by three phases, two of them with well-known thermoelectric properties, Bi 2Ca2Co 1.7Ox and Ca 3Co 4O 9, was obtained for the first time when the growth process was performed with a 300 mA applied current. Under these conditions the thermoelectric performances of this new composite reach values above the highest ones reported in the literature for polycrystalline Bi 2Ca2Co 1.7Ox materials.
