%X The effect of density on the thermoelectric properties of the filled skutterudite compound La0.75Fe3CoSb12 was investigated. The La0.75Fe3CoSb12 showed p-type conduction. The mobility increased with an increase in density. The electrical resistivity increased and the thermal conductivity decreased with decreasing density due to the pores scattering. The Seebeck coefficient is independent of density. The portion of electrical resistivity increase is consistent with that of the thermal conductivity reduction. The value of ZT of the specimen with low density is compared to that of specimen with high density. The value of ZT does not depend on density.
