Notes:
Ag1-xPbmSbTe2+m (m = 6, 10, 18; x = 0, 0.5, 0.75) compounds were prepared by melting-sparkplasma sintering (SPS) process. The effects of m and x on the thermoelectric properties of the compoundswere investigated. The results indicate that all samples are n-type conduction. For Ag1-xPb18SbTe20 (x = 0,0.5, 0.75), the electrical conductivity decreases, whereas Seebeck coefficient increases, with increasingAg concentration. For AgPbmSbTe2+m (m = 6, 10, 18), as m increases, the Seebeck coefficient slightlydecreases and the electrical conductivity increases first, with a maximum at m =10, and then decreases.The thermal conductivity increases with increasing m
