Abstract
Using the solid reaction method, it was possible to prepare composites of Ca2.95Sr0.05Co4O9+δ /Ag (Ca349-Sr/Ag). Its transport properties were studied in the temperature range between 80K and 300K by measurements of Seebeck coefficient S(T), thermal conductivity κ(T) and electrical resistivity ρ(T). The thermoelectric performance was determined through the calculation of the power factor PF and the dimensionless merit figure ZT, these parameters reached maximum values close to 13μW/K2-cm and 0.18, respectively. The observed increase in thermoelectric performance is the result of the combined effects of substitution of Sr by Ca and the addition of silver on the transport properties of composite. The results obtained make these structures promising materials to be used in the design of thermoelectric devices useful in applications at low temperatures.
