ABSTRACT
 
Rare earths filled Skutterudite are known for their improved thermoelectric properties and thus materials based on such structures are promising candidates for specific applications. Also, reduced grain size is considered a promising route to decrease the thermal conductivity of materials and therefore to improve the figure of merit of thermoelectric materials.
Here we present preliminary results concerning physical properties of RE-(Fe,Ni)4Sb12 nanostructurated skutterudite (RE = Y, Ce, Yb) obtained by spark plasma sintering of nanopowders.
Keywords: Skutterudite; Yb-(Fe, Ni)4Sb12 and Er(Fe, Ni)4Sb12 compounds; Spark plasma sintering.
