Abstract
High figure of merit, 2.6x10(-3)K(-1) at 25 degrees C, was achieved in p-type bismuth telluride ceramics fabricated by hot-isostatically pre ssing the pulverized metallic powder mixtures, Pulverization behavior of the metallic powders obeyed the Rittinger's low and the resultant t hermoelectric properties depended on the pulverizing conditions, Disso lution-condensation mechanism for densification gave rise to the isotr opic microstructure and hence isotropic thermoeletric characteristics.
