Indium-filled CoSb3 materials have been investigated by combining hydrothermal synthesis and hot pressing. The materials were prepared as follows. Corresponding nanopowders were synthesized by a hydrothermal synthesis method, in some cases followed by melting at 1373 K, and then hot pressed at 923 K. The phase composition and microstructure of the bulk materials were analyzed by conventional methods, such as x-ray diffraction (XRD), scanning electron microscopy (SEM), and field-emission SEM equipped with energy-dispersive x-ray spectroscopy (EDS). The thermoelectric properties of the bulk materials were measured from room temperature to 773 K. The results reveal that indium can be successfully filled into the voids of the CoSb3 structure when the sample preparation procedure contains melting. The influence of the processing on the thermoelectric properties of the materials is also discussed.
