摘要：

Sinter-forging technique was applied to produce high efficiency epsilon-Zn4Sb3 bulk specimens. Near single phase Zn4Sb3 with a remnant ZnSb was obtained using nominal stoichiometric powder mixtures. Thermoelectric properties in sinter-forged specimens as a function of temperature were investigated up to 600 K and compared with results of other studies. Transport properties at room temperature were also evaluated. Thermoelectric properties of Zn4Sb3 processed by sinter-forging are comparable to the published data. Sinter-forging offers a potential processing route to produce a bulk Zn4Sb3. (C) 2004 Elsevier B.V. All rights reserved.
