Bulk Mechanical Alloying (BMA) is proposed to produce p-type Bi<SUB>2</SUB>Te<SUB>3</SUB>-Sb<SUB>2</SUB>Te<SUB>3</SUB> 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.<BR>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.
