Abstract
The thermal stability of skutterudite-based thermoelectric modules is of great importance since they are used at elevated temperatures. This study examined the high-temperature stability of In-filled and Fe-doped skutterudites (In0.25Co3FeSb12) as a function of the following aging variables: atmosphere (vacuum and air), temperature, and time. Sb-based oxides are produced preferentially on exposure to high temperatures in air. The oxide layer produced during aging at 823 K in air was much thinner than that produced during aging at 723 K in air. The formation of InSb is believed to retard the oxidation of Sb and act as an obstacle to the growth of the oxide layer. The CoSb3-based skutterudites were stable at 823 K if they were not exposed to air, and InSb phases were not produced in the In0.25Co3FeSb12 skutterudites.
