dc.description.abstractA new thermoelectric material for the generation of electricity above room temperature has been prepared. It is constructed of innershield cored wire, a crystalline material such as Cs2CoCl4 and constantan. Its average Seebeck coefficient was measmed to be α ~830μV/K, resistivity has been moderate at around ρ~ 3x10-2Ωcm, thermal conductivity κ~1.03x10-2W/mK, yield η~0.2255 and figure of merit Z~5.16x10-3K-1 for a temperature difference ∆T~422K, where the high temperature was Th~736K and the cold temperature Tc~314K. These results were compared with those obtained from materials commercially prepared for these same aims. According to the spectroscopic X-rays analysis, the material is made up of Cs3CoCl5, Fe1.874Sn0.096O3, Co6C(CO)12S2, and Ba4In6O13 whose respective crystalline structures are tetragonal, hexagonal, monoclinic and orthorhombic.en_US

El mismo se construye a partir de alambres con alma fundente, material cristalino tal como Cs2CoCl4 y constantán. Se ha medido su coeficiente de Seebeck promedio α ~830μV/K , resistividad ρ~ 3x10-2Ωcm, conductividad térmica κ~1.03x10-2W/mK, rendimiento η~0.2255 y figura de mérito Z~5.16x10-3K-1 a una diferencia de temperatura ∆T~422K, donde la temperatura de la parte caliente Th~736K y en la parte fría Tc~314K. Estos resultados fueron comparados con los que se obtienen de materiales comerciales preparados para estos mismos fines.
