Type: article
Abstract: Single-phase filled skutterudite compounds,CeyFexCo4- xSb12(x=0—3.0，y=0—0.74)，were synthesized by a melting metho d.Effect of Fe content on Ce filling fraction,the crystal structure and the ther moelectric transport properties of CeyFexCo4-xS b12 saturated by Ce were investigated.Ce filling fraction increased l inearly with increasing Fe content.The lattice constants a of CeyFexCo4-xSb12 increased with increasing Fe content a nd Ce filling fraction.All samples showed p-type conduction.Hall coefficient RH decreased with increasing Fe content.Hole concentration p and electri cal conductivity σ increased with increasing Fe content.Seebeck coefficient α decreased with increasing Fe content.While Fe/Co ratio was about 1.5/2.5,the lat tice thermal conductivity (κl) reached the minimum values.
