Title: High-performance Ag{sub 0.8}Pb{sub 18+x}SbTe{sub 20} thermoelectric bulk materials fabricated by mechanical alloying and spark plasma sintering

Abstract

Polycrystalline Ag{sub n}Pb{sub m}SbTe{sub m+2n} thermoelectric materials, whose compositions can be described as Ag{sub 0.8}Pb{sub 18+x}SbTe{sub 20} were prepared using a combined process of mechanical alloying and spark plasma sintering. Electric properties of the sintered samples with different Pb contents were measured from room temperature to 700 K. The maximum power factor of 1.766 mW/mK{sup 2} was obtained at 673 K for the Ag{sub 0.8}Pb{sub 22}SbTe{sub 20} sample, which corresponds to a high dimensionless figure of merit, ZT=1.37. This best composition is different from that reported before.
