抄録
The filled skutterudite compounds, MyFexCo4-xSb12 (x=0-1.0, y=0-0.15, M=Ce, La, Y), were prepared by a new solid state reaction method using Co, Fe, Sb, CeCl3.6H2O, LaCl3.6H2O and YCl3.6H2O powders, and their thermoelectric properties were investigated. MyFexCo4-xSb12 (x=0-1.0, y=0-0.15, M=Ce, La, Y) compounds showed p-type conduction. The electrical conductiviy (σ) increased with increasing Fe content. The Seebeck coefficient (α) increased with increasing Fe content for MFexCo4-xSb12, but decreased with increasing Fe content for FexCo4-x, Sb12. The Lattice thermal conductivity (KL) decreased significantly with the substitution of Fe for Co and the filling of M (M=Ce, La, Y) into the Sb icosahedral voids, while the carrier thermal conductivity (Kcar) was not much affected by the Fe substitution and the M (Ce, La, Y) filling. The thermoelectric figure of merit was improved by the combinatior of Fe substitution and M (Ce, La, Y) filling.
