从FexIn 4 − xSe 3（x= 0，0.05，0.1，0.15）的元素粉末混合物开始，通过机械合金化（MA）和热压（HP）制备具有均匀微观结构的多晶In 4 Se 3基化合物。随着x从0增加到0.15，电阻率和塞贝克系数的绝对值增加，而热导率先减小后增大。在723 K时，FexIn 4 − xSe 3（x= 0.05）样品的最大无量纲优值ZT为0.44。
Starting from elemental powder mixtures of FexIn4−xSe3(x= 0, 0.05, 0.1, 0.15), polycrystalline In4Se3-based compounds with homogeneous microstructures were prepared by mechanical alloying (MA) and hot pressing (HP). With the increase ofxfrom 0 to 0.15, the electrical resistivity and the absolute value of the Seebeck coefficient increased, while the thermal conductivity first decreased and then increased. The maximal dimensionless figure of meritZTof 0.44 was obtained for the FexIn4−xSe3(x= 0.05) sample at 723 K.
