SKUTTERUDITE BASED INTERSTITIAL ALLOY, METHOD FOR ITS PRODUCTION, AND THERMOELECTRIC CONVERTER MANUFACTURED USING THIS ALLOY Russian patent published in 2007 - IPC H01L35/18 H01L35/34

Abstract RU 2300160 C2

FIELD: thermoelectric materials.

SUBSTANCE: source alloy material incorporating rare earth metal R which is one of elements chosen among La, Ce, Pr, Nb, Sm, Eu, and Yb, transition metal T which is one of elements chosen among Fe, Co, Ni, Os, Ru, Pb, Pt, and Ag, as well as metal antimony Sb are melted. Melt is quickly cooled down by way of strip casting at cooling rate of 10² to 10⁴ °C per second as measured at melt temperature ranging up to 800 °C until hardened product is attained. This product is essentially skutterudite based interstitial alloy suited to use for thermoelectric component.

EFFECT: enlarged quantity of alloy of almost uniform metallographic structure produced without additional heat treatment, reduced cost of thermoelectric cell manufacture.
