Structural and thermoelectric properties of sintered silicon clathrates: Ba6Eu2Ga16Si30 nominal composition

We have prepared Ba8−xEuxGa16Si30 clathrate system by spark plasma sintering method at different temperatures 1093-1273 K using a starting material with Ga rich composition Ba6Eu2Ga17Si29. Powder x-ray diffraction (XRD), Rietveld structure refinement, FE-SEM and EPMA indicate that the Ga composition...
