C.Improved thermoelectric performances in textured Bi1.6Pb0.4Ba2Co2Oy/Ag compositesART-2016-97593Bi1.6Pb0.4Ba2Co2Oy 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.2016http://zaguan.unizar.es/record/7083310.1016/j.ceramint.2016.08.202http://zaguan.unizar.es/record/70833oai:zaguan.unizar.es:70833info:eu-repo/grantAgreement/ES/DGA/T12info:eu-repo/grantAgreement/ES/DGA/T87info:eu-repo/grantAgreement/ES/MINECO/MAT2013-46505-C3-1-RCeramics International 42, 16 (2016), 18592-18596by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
