Thermoelectric properties of semi conducting compound Sb^sub 71.22^Co^sub 2.97^Fe^sub 20.77^Ce^sub 5.04

Hot-pressed samples of the semi-conducting compound Sb^sub 71.22^Co^sub 2.97^Fe^sub 20.77^Ce^sub 5.04^ were prepared and characterized by X-ray thermal differential analysis and microprobe analysis. Thermoelectric characterization was done through measurements of the electrical and thermal conductivities as well as the Seebeck coefficient between room temperature and 900 K. All samples had p-type conductivity. The dimensionless thermoelectric figure of merit ZT increases with increasing temperature and reaches a maximum value of 1.22 at 873 K.[PUBLICATION ABSTRACT]
