Universidad de Zaragoza (orcid)0000-0001-7056-0546 Improved thermoelectric performances in textured Bi1.6Pb0.4Ba2Co2Oy/Ag composites 2016 Access copy available to the general public Unrestricted Bi1.6Pb0.4Ba2Co2Oy thermoelectric ceramics with small Ag additions (0, 1, 3, and 5 wt%) have been textured using the laser floating zone method. Microstructure has shown a slight decrease on the secondary phases content and a better grain alignment in Ag added samples. These microstructural features are reflected in the thermoelectric properties, which have shown a significant decrease of electrical resistivity, when the Ag content is raised. In spite of a corresponding decrease of Seebeck coefficient, all the Ag-containing samples possess higher Power Factor values than the Bi1.6Pb0.4Ba2Co2Oy ones. Moreover, the maximum Power Factor values (about 0.36 mW/K2.m at 650 °C) have been measured in Bi1.6Pb0.4Ba2Co2Oy+3 wt% Ag samples, which are the best results reported in this family of materials. info:eu-repo/grantAgreement/ES/DGA/T12 info:eu-repo/grantAgreement/ES/DGA/T87 info:eu-repo/grantAgreement/ES/MINECO/MAT2013-46505-C3-1-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.986 2016 MATERIALS SCIENCE, CHARACTERIZATION & TESTING 2 / 26 = 0.077 2016 Q1 T1 MATERIALS SCIENCE, CERAMICS 2 / 26 = 0.077 2016 Q1 T1 0.843 2016 Electronic, Optical and Magnetic Materials 2016 Q1 Ceramics and Composites 2016 Q1 Surfaces, Coatings and Films 2016 Q1 Process Chemistry and Technology 2016 Q1 Materials Chemistry 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Rasekh, S.
