Synthesis and thermoelectric properties of CoSb3 compounds by spark plasma sintering
Materials Letters 58(2004)1981-1984，-0001，（）：
Single-phase polycrystalline CoSb3 skutterudite thermoelectric compounds have been synthesized by spark plasma sintering (SPS) and the thermoelectric properties including Seebeck coefficient, electrical resistivity and thermal conductivity are measured from room temperature to 800 K. The CoSb3 compound with relative density of 97.4% and grain size of about 100 nm is achieved under the sintering condition of 873 K for 5 min, and a maximum thermoelectric dimensionless figure of merit value of 0.095 is obtained at about 673 K.
