采用高压高温（HPHT）法制备了InxPbxCo 4Sb 12。采用X射线衍射（XRD）、电子探针分析和热电性能测试对样品进行了表征。在323- 723 K温度范围内对InxPbxCo 4Sb_（12）样品的塞贝克系数、电阻率和热导率进行了测试。随着合成压力的增加，在1.5 GPa ~ 2.3 GPa范围内合成的In0.5Pb0.1Co4Sb12样品的Seebeck系数明显增大，热导率则大幅度降低。
We prepared InxPbxCo4Sb12 by high-pressure and high-temperature (HPHT) method. Samples were characterized by X-ray diffraction (XRD), electron microprobe analysis and thermoelectric properties measurements. The Seebeck coefficient, electrical resistivity and thermal conductivity of InxPbxCo4Sb12 samples were all performed in the temperature range of 323–723K. With the increasing synthetic pressure, the Seebeck coefficient of In0.5Pb0.1Co4Sb12 samples, which synthesized between 1.5 GPa–2.3 GPa, showed an obvious increase while the thermal conductivity exhibited a substantial reduction.
