Abstract

We report on the thermoelectric properties of the filled skutterudite Ce0.9Fe3CoSb12 prepared via non-equilibrium synthesis method. Melt-spun ribbons were directly converting into single phase polycrystalline pellets under pressure. For comparison, pellets with the same composition were also prepared using the conventional solid-state reaction followed by long term annealing. It was found that the non-equilibrium synthesized samples have higher power factors and lower thermal conductivity, leading to substantially higher figure of merit.
