抄録

Mechanical alloying followed by pulse discharge sintering (MA-PDS) was employed to synthesize the bulk (Bi,Sb)2Te3 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)2Te3 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.
