New promising Co-free thermoelectric ceramic based on Ba-Fe-oxide 2013 Thermoelectric ceramics are based in a limited number of transition metal oxides (Co, Mn, Ni,…) which produce materials with high thermoelectric performances. Based on previously existing thermoelectric phases, the phase diagram equilibrium can help to design new thermoelectric ceramics based on other transition metals (for example, Fe). In this work, BaFeOx ceramics have been prepared by the classical solid state method using different sintering temperatures. The produced materials have shown promising thermoelectric properties when treatment temperatures are in the perovskite zone domain of the phase equilibrium diagram. In spite of the good values for the Seebeck coefficients, power factor is low due to the high resistivities measured in all cases. info:eu-repo/grantAgreement/ES/DGA/T12 info:eu-repo/grantAgreement/ES/DGA/T87 info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 1.966 2013 ENGINEERING, ELECTRICAL & ELECTRONIC 62 / 246 = 0.252 2013 Q2 T1 PHYSICS, CONDENSED MATTER 29 / 67 = 0.433 2013 Q2 T2 PHYSICS, APPLIED 45 / 135 = 0.333 2013 Q2 T2 MATERIALS SCIENCE, MULTIDISCIPLINARY 79 / 246 = 0.321 2013 Q2 T1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Diez,J.
