Abstract :
An attempt was made to synthesize β-Zn4Sb3 semiconducting compound by PIES (Pulverized and Intermixed Elements Sintering)/hot-pressing method. We found that it is possible to synthesize β-Zn4Sb3 as a major phase without increased temperature when we start the ball milling process with a Zn-rich composition. The power factor α2/ρ at room temperature was 6.3×10-4 W/mK2 and these initial data clarified that relatively high performance can be achieved with the PIES/hot-press method
