摘要：

Micro-sized powder of N-type Ag0.8PbmSbTem+2(m=12, 14, 16, 18) alloy was fabricated via a vacuum sealed melting method combined with high energy ball milling. Rapid hot-pressing sintering was employed to prepare bulk thermoelectric materials at 673K with sintering pressure of 20MPa, and time of 30min, respectively. The influence of rapid hot-pressing sintering method and variation in the value of m on the structure and the thermoelectric properties was investigated. The maximum Seebeck coefficient of-634 μV/K is obtained at 348K with m equaling to 16. The power factor reaches a maximum value of 7.5 × 10-4W/(m &middot K2) at 548K for an m of 18.
