| 摘 要： | 用固相反应法在900—1000K温度范围和x＝0—10的组成范围内合成了单相Co基Skutterudite化合物FexCo4-xSb12，并对化合物的结构和热电特性影响进行了研究.结果表明：化合物的晶格常数随Fe置换量的增加线性增加，载流子浓度和电导率随Fe置换量的增加而增加，Seebeck系数随Fe置换量的增加而减少，Seebeck系数的峰值温度随Fe置换量的增加向高温方向移动，晶格热导率由于Fe的置换而大幅度下降，并随Fe的置换量的增

| Abstract: | Skutterudite compounds FexCo4-xSb12 were synthesizedby solid state reaction using high-purity powders of Co,Fe,and Sb as starting materials.FexCo4-xSb12(x＝0—10) compounds were obtained at 900—1000K.The lattice constant of FexCo4-xSb12 increased with increasing substitution of Fe for Co sites.Carrier concentration and electrical conductivity increased with increasing Fe content.Seebeck coefficient decreased and Topt of Seebeck coefficient shifted to higher temperature with increasing Fe content.Lattice conductivity was reduced significantly by substitution of Fe for Co sites.The maximum ZT value of 05 was obtained for Fe0.92Co3.08Sb12 at 750K. |
