The single_phase double_atom_filled p_type BamCenFeCo3Sb12 c ompounds were synthesized using the solid_state reaction method and also the melt reac tion method. Thermoelectric properties of the p_type BamCenFeCo3Sb 12 compound were investigated, and the results indicated that the electri cal conductivity of the p_type BamCenFeCo3 Sb12 is intervenient between the electrical conductivities of single_atom _filled compounds BamFeCo3Sb12 and CenFeCo3Sb12.It d ecreased with increasing Ba and Ce fill ing fraction. With the same filling fraction, the lattice thermal conductivity o f BamCenFeCo3Sb12 is found to be smaller than that of Ba mFeCo3Sb12 and CenFeCo3Sb12.
