摘要：
Semiconductor material has great potential for power generation applications. Zn4Sb3 has emerged as one of the most promising thermoelectric materials, since it shows a high figure of merit value in an intermediate temperature range (450K-650K). We prepare the samples of Zn4Sb3 and Zn4Sb3 mixed with La by the mechanochemical method. The phase composition and transformation in this alloy system during mechanical alloying is investigated with X-ray diffraction(XRD), laser grain size analysis and differential scanning calorimetry(DSC) respectively. The results of laser particle size analysis show...
