摘要：

Sn-filled (Fe,Co)Sb-3 skutterudites of the form of SnyFe3Co5Sb24 (0 <= y <= 1.5) were synthesized by the mechanical alloying of elemental powders followed by vacuum hot pressing. The phase transformations that occur during both mechanical alloying and vacuum hot pressing were examined by X-ray diffraction. Single-phase Sn-filled skutterudite was successfully produced by vacuum hot pressing using as-milled powders without subsequent annealing. The thermoelectric properties of the hot-pressed specimens were evaluated as a function of temperature and tin content. The void filling of tin (up to y = 1.0) in Fe3Co5Sb24 appeared to increase the thermoelectric figure of merit.
