Abstract:Polycrystalline skutterudite Ba 0.4 Co 4 Sb 11.7 Te 0.3 with a bcc crystal structure was prepared by the HighPressure and High-Temperature (HPHT) method. The study explored a chemical method for introducing Ba atoms into the voids of CoSb 3 to optimize the thermoelectric figure of merit ZT in the system of Ba 0.4 Co 4 Sb 11.7 Te 0.3. The samples were characterized by X-ray diffraction, electron microprobe analysis, and thermoelectric properties measurement. The electrical resistivity, Seebeck coefficients and … Show more
