由于原料储量丰富、成本低、无毒等特点，镁硅化合物在中温温区热电发电中的应用引起了国际热电界的广泛关注。在本工作中，我们采用两步固相反应和放电等离子烧结工艺制备了一系列Sb掺杂的Mg-2.16(Si0.4Sn0.6)(1-y)Sb-y(0
Due to the rich reserves of the raw materials, along with their low cost and nontoxic nature, Mg2Si1-xSnx-based compounds have generated intense attention from the international thermoelectric community for their application in thermoelectric power generation within the intermediate temperature range. In this work, we have adopted a two-step solid state reaction followed by a spark plasma sintering process to prepare a series of Sb-doped Mg-2.16(Si0.4Sn0.6)(1-y)Sb-y (0
