Fabrication of Ag—Sn—Sb—Te Based Thermoelectric Materials by MA-PAS and Their Properties. — AgSn18SbTe20 and Sn50Te50 thermoelectric materials are pre-pared by mechanical alloying from powder mixtures of the elements followed by plas-ma-activated sintering (653 K, 15 min). The maximum power factor of 1.98·10-3 Wm-1K-2 is obtained at 723 K for AgSn18SbTe20 which is higher than those of NaSn18SbTe20 and SnTe reported previously. Ag and Sb codoped SnTe compounds ex-hibit better electrical properties than undoped SnTe compounds within some tempera-ture range. — (WU, J.; YANG*, J.; ZHANG, H.; ZHANG, J.; FENG, S.; LIU, M.; PENG, J.; ZHU, W.; ZOU, T.; J.
