     the high-temperature thermoelectric properties of in x co4sb12 (0.05 ≤ x ≤ 0.40) skutterudite compounds were investigated in this study. the phase states of the samples were identified by x-ray diffraction analysis and field-emission scanning electron microscopy at room temperature. insb and cosb2 were found as secondary phases in samples with x = 0.10 to 0.40. the filling limit of in into the cosb3 cages of in x co4sb12 was in the range 0.05 < x < 0.10. the electrical resistivity, seebeck coefficient, and thermal conductivity of the in x co4sb12 samples were measured from room temperature to 773 k. the seebeck coefficient of all samples was negative. reduction of the thermal conductivity by in addition resulted in a high thermoelectric figure of merit (zt) of 0.67 for in0.35co4sb12 at 600 k.
