Zusammenfassung: | Bulk textured Ca2.5(RE)0.5Co4O9 (RE, rare-earth element=Pr, Nd, Eu, Dy and Yb) ceramics have been prepared using sinter-forging technique. Both sintered and sinter-forged samples have been prepared and characterized. We present the thermoelectric properties, structural and microstructural investigations of the samples which show a strong degree of crystallite orientation. In addition, the effect of the rare-earth substitution on the properties is discussed. |
