以agsn18sbte20和Sn50Te50的单质粉末混合物为原料，采用机械合金化（MA）和等离子活化烧结（PAS）相结合的方法制备了p型agsn18sbte20和Sn50Te50块状热电材料。结果表明，仅研磨1h即可制备出SnTe化合物。随着铣削时间的延长，Ag和Sb原子逐渐扩散到初生SnTe化合物的晶格中，形成了SnTe基固溶体。在323K ~ 723K范围内测量了试样的电阻率和塞贝克系数。agsn18sbte20在673K时获得了1.98×10−3Wm−1K−2的最大功率因数，高于之前发表的类似成分的材料。
Starting from elemental powder mixtures of AgSn18SbTe20and Sn50Te50, P-type AgSn18SbTe20and Sn50Te50bulk thermoelectric materials were fabricated by a combined process of mechanical alloying (MA) and plasma activated sintering (PAS). It was found that SnTe compound could be easily synthesized after milling only for 1h. Prolonging the milling time, Ag and Sb atoms diffused into the lattice of the primary SnTe compound gradually and SnTe-based solid solution was formed. The electrical resistivity and Seebeck coefficient of the as-PASed samples were measured from 323K to 723K. The maximum power factor of 1.98×10−3Wm−1K−2was obtained at 673K for AgSn18SbTe20and it was higher than that of the material with similar composition from previous published literature.
