Abstract

Bulk Mechanical Alloying (BMA) is proposed to produce p-type Bi₂Te₃-Sb₂Te₃ thermoelectric materials with large yield and without any contamination. Because of the solid-state alloyment through this process, no melting nor solidification process is necessary to yield the targeting composition of this type of thermoelectric materials. Furthermore, hot pressing is applied for densification by varying both the pressure and the holding temperature. Process parameter dependency of thermoelectric properties is investigated for three different BMA samples.
