| 中文摘要 | A series of high-textured Ag-doped or/and Ag-added Ca(3)Co(4)O(9) ceramic specimens have been prepared by a cold-pressing technique and their thermoelectric properties were compared from room temperature to 1000 K. The substitution of Ag(+) for Ca(2+) causes the reduction of resistivity and the enhancement of thermoelectric power simultaneously, whereas the addition of metal Ag results in the decrease on resistivity together with thermoelectric power. Both Ag(+) doping and Ag addition can enhance power factor; however, the doping of Ag(+) is advantageous for the suppression of thermal conductivity whereas the addition of Ag facilitates thermal conductivity. Ca(2.7)Ag(0.3)Co(4)O(9)/Ag-10wt% composite exhibits a quite respectable thermoelectric performance; the dimensionless figure of merit ZT can reach 0.5 at 1000 K. (C) 2008 Elsevier B.V.
