Notes:
Single-phase double atoms filling skutterudite compounds were synthesized by usingmelting reaction method. The effects of double atoms filling on the structure and lattice thermalconductivity of skutterudite compounds were investigated. The results of Rietveld refinement indicatethat CamCenFexCo4-xSb12 compounds possess skutterudite structure and the Sb-icosahedron voids havebeen partially filled with filling atoms. With the same filling fraction, the lattice thermal conductivity ofCamCenFexCo4-xSb12 is smaller than that of CamFexCo4-xSb12 and CenFexCo4-xSb12, furthermore, when thetotal filling fraction (m+n) is about 0.3 and respective filling fraction of Ca and Ce are approximatelyequal, the lattice thermal conductivity is the least
