| Abstract: | The synthesis approaches and its characteristic of skutterudite compounds, such as smelting, solid-state reaction, mechanical alloying and spark plasma sintering etc were reviewed. In addition, some optimizations and latest progresses to improve the thermoelectric properties of skutterudite compounds, including substitution of Fe, Ni, and alkaline earth or rare earth filling were expounded, and the influences of low dimension on thermoelectric transport mechanism were also introduced. Some detailed investigations to further improve the thermoelectric properties were revealed. |
