Rapid fabrication of Se-modified skutterudites obtained via self-propagating high-temperature synthesis and pulse plasma sintering route
Abstract
Selenium is an effective dopant in skutterudite-based thermoelectric materials. It strongly influences thermaltransport properties due to effective phonon scattering. This study proposes a short-term fabrication route to SemodifiedCoSb3-based materials. Alloy synthesis was conducted via self-propagating high-temperature synthesis.Subsequently, pulse plasma sintering consolidated all materials. As a result, thermoelectric materials with highelectrical properties homogeneity were obtained. Seebeck potential mapping showed the measured deviation ofthe Seebeck coefficient for all fabricated samples was between 5 and 7%. A very low thermal conductivity (1.59W mက00 1 Kက00 1, at 573 K) was achieved for the highest doped sample, and one of the lowest reported results obtainedfor bulk skutterudite-based thermoelectric materials ever. This resulted in a low lattice thermal conductivity(1.51 W mက00 1 Kက00 1, at 573 K). This led to the highest ZT (0.27 at 623 K) for the highest doped sample.
