摘要：

In this study, we present the fabrication and thermoelectric properties of MgAgSb composites. The fabrication process was based on the concept of nanoparticle engineering. Mg3Sb2 and Ag3Sb nanopowders were first synthesized and subsequently used for MgAgSb formation. The effects of Mg2Cu, Mg2Ni, and Mg2Sn as doping species on thermoelectric properties were studied. Compared with the intrinsic MgAgSb, the electrical conductivity was improved by the Ni and Sn dopants. In contrast, the Cu dopant causes MgAgSb to have a lower ZT. Our experimental results proved that the nanoparticle engineering process can be used for the fabrication of MgAgSb-based thermoelectric composites.
