Thermoelectric (TE) power generation is increasingly drawing attention as a viable technology to make significant contributions towards recovering waste heat and increasing energy efficiency of heat engines. TE devices are the semiconductor systems that can either directly convert thermal energy into electricity for power generation, or perform cooling or heating with electric power. Recent studies showed that the powder metallurgy methods have been attaining best TE properties as well as mechanical properties. Gas atomization is one of the novel and special category of rapid solidification method for fabrication of high compatibility, homogeneous and fine grain structured TE materials to enhance TE efficiency as well as mechanical strength. In this research, we have fabricated thermoelectric alloys by gas atomization process, and then subsequently consolidated by SPS. The maximum figure of merit, ZT is achieved for nanostructured bulk samples owing to the reduction of lattice thermal conductivity due to scattering of phonons.
