Powder preparation and thermoelectric properties of Mg2Si-based materials

碩士 === 國立成功大學 === 材料科學及工程學系 === 103 === Due to the difference of melting point amomg Mg, Si and Sb elements, it is not easy to synthesize Mg2Si -based alloy by melting method. In this study, Mg2Si-based thermoelectric bulks were fabricated by solid-state reaction and hot-pressed sintering (HP, SPS)....

In this study, Mg2Si-based thermoelectric bulks were fabricated by solid-state reaction and hot-pressed sintering (HP, SPS). The results show that with the increase of Sb-doping in Mg2Si, the electrical conductivity (σ) increase, and the Seebeck coefficient increase slightly at higher temperature. The power factor of Mg2Si -based bulks was improved by Sb doping. The maximum value of the power factor, PF, is 1.03 mW/m-k2 at 765K for the Mg2.16(Si0.4Sn0.6)0.975Sb0.025 bulk.
