Compósitos de Ca349-Sr/Ag como material para aplicaciones termoeléctricas de baja temperatura
Using the solid reaction method, it was possible to prepare composites of /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 13 μW/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.
期刊介绍：
The Journal of the Spanish Ceramic and Glass Society publishes scientific articles and communications describing original research and reviews relating to ceramic materials and glasses. The main interests are on novel generic science and technology establishing the relationships between synthesis, processing microstructure and properties of materials. Papers may deal with ceramics and glasses included in any of the conventional categories: structural, functional, traditional, composites and cultural heritage. The main objective of the Journal of the Spanish Ceramic and Glass Society is to sustain a high standard research quality by means of appropriate reviewing procedures.
