Abstract: | The ceramics with Ba[1–x]Sr[x]Pb[1+y]O[3+2y] (x = 0.6, 0.8, y = 0.00, 0.10, 0.20) composition was prepared using solid-state reactions method and its phase composition, crystal structure, electrical conductivity, thermal conductivity and thermo-EMF was studied. The electronic and lattice parts of the thermal conductivity of ceramics were determined and its power factor (P) and figure-of-merit values (ZT) were calculated. It was found, that the best thermoelectric characteristics at high temperatures had the ceramics with composition Ba[0.2]Sr[0.8]Pb[1.1]O[3.2] (P1000 = 1.36 mW/(m · K2), but near the room temperature – the Ba[0.2]Sr[0.8]Pb[1.2]O[3.4] sample (ZT[423] = 0.033). On the basis of Ba[0.2]Sr[0.8]Pb[1.1]O[3.2 ](n-type conductor) and Na[0.55]Co[0.9]Ni[0.1]O[2] (р-type conductor) ceramics the prototype of the thermoelectric module was produced and its working characteristics (open-circuit voltage and power) at different temperatures were determined. |
