Universidad de Zaragoza (orcid)0000-0002-0794-3998 From nanosized precursors to high performance ceramics: the case of Bi2Ca2Co1.7Ox 2017 Access copy available to the general public Unrestricted Bi2Ca2Co1.7Ox thermoelectric ceramics were prepared by four different synthesis routes: coprecipitation with ammonium carbonate or oxalic acid, attrition milling, and solid state (as reference). Microstructure showed that coprecipitation and attrition milling produced sintered materials with less porosity and smaller particle sizes than the solid state ones. Thermoelectric properties reflect the microstructure, leading to materials with lower electrical resistivity and higher Seebeck coefficient, when compared with the solid state ones. In spite of an increase in thermal conductivity in these samples due to their lower porosity, the maximum estimated Figure-of-Merit is higher than in sintered materials. info:eu-repo/grantAgreement/ES/DGA-FEDER/T12 info:eu-repo/grantAgreement/ES/DGA-FEDER/T87 info:eu-repo/grantAgreement/ES/MINECO-FEDER/MAT2013-46505-C3-1-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.687 2017 PHYSICS, APPLIED 44 / 146 = 0.301 2017 Q2 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 97 / 283 = 0.343 2017 Q2 T2 0.782 2017 Mechanical Engineering 2017 Q1 Mechanics of Materials 2017 Q2 Condensed Matter Physics 2017 Q2 Materials Science (miscellaneous) 2017 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Rasekh, Sh.
