Mechanical alloying followed by pulse discharge sintering (MA-PDS) was employed to synthesize the bulk (Bi,Sb)<sub>2</sub>Te<sub>3</sub> thermoelectric materials with P, Ag or both additions. The effect of P and Ag on the microstructure and thermoelectric performance of the compacts were investigated. The dispersed P particles are found to decrease the size of (Bi,Sb)<sub>2</sub>Te<sub>3</sub> crystallites and inhibit the densification of the alloyed powders, while the added Ag is effective in raising electrical conductivity. On the contrary, addition of P in combination with Ag does not generate a favorable thermoelectric properties.
