The synthesis and thermoelectric properties of double-atom-filled BamCenFeCo3Sb12 compounds
|
Abstract:
The single_phase double_atom_filled p_type Ba m Ce n FeCo 3Sb 12 compounds were synthesized using the solid_state reaction method and also the melt reaction method. Thermoelectric properties of the p_type Ba m Ce n FeCo 3Sb 12 compound were investigated, and the results indicated that the electrical conductivity of the p_type Ba m Ce n FeCo 3Sb 12 is intervenient between the electrical conductivities of single_atom_filled compounds Ba m FeCo 3Sb 12 and Ce n FeCo 3Sb 12 .It decreased with increasing Ba and Ce filling fraction. With the same filling fraction, the lattice thermal conductivity of Ba m Ce n FeCo 3Sb 12 is found to be smaller than that of Ba m FeCo 3Sb 12 and Ce n FeCo 3Sb 12 .
