Microstructural analysis of as-grown samples has shown the formation of well-aligned thermoelectric grains together with a relative high amount of secondary phases. On the other hand, a short (24 h) thermal treatment (810 °C for Sr, 800 °C for Ca, and 750 °C for Ba) under air, raises of thermoelectric phase content through the recombination of the secondary ones. These microstructural modifications led to a large decrease of electrical resistivity, improving the power factor. These results have been compared with samples prepared by the conventional solid state method and with the best values reported in the literature. From these data, it is possible to deduce that the high thermoelectric characteristics obtained in these samples make them very attractive for practical applications. 000069660 536__ $$9info:eu-repo/grantAgreement/ES/DGA/T12$$9info:eu-repo/grantAgreement/ES/DGA/T87$$9info:eu-repo/grantAgreement/ES/MINECO/MAT2013-46505-C3-1-R 000069660 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttps://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 000069660 590__ $$a1.633$$b2018 000069660 591__ $$aMATERIALS SCIENCE, CERAMICS$$b10 / 28 = 0.357$$c2018$$dQ2$$eT2 000069660 592__ $$a0.377$$b2018 000069660 593__ $$aCeramics and Composites$$c2018$$dQ2 000069660 593__ $$aMechanics of Materials$$c2018$$dQ2 000069660 593__ $$aIndustrial and Manufacturing Engineering$$c2018$$dQ2 000069660 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000069660 700__ $$0(orcid)0000-0003-3466-9952$$aRasekh, S. 000069660 700__ $$0(orcid)0000-0002-0794-3998$$aMadre, M.A.$$uUniversidad de Zaragoza 000069660 700__ $$0(orcid)0000-0003-3995-5763$$aTorres, M.A.$$uUniversidad de Zaragoza 000069660 700__ $$0(orcid)0000-0001-7056-0546$$aSotelo, A.E.$$uUniversidad de Zaragoza 000069660 7102_ $$15002$$2305$$aUniversidad de Zaragoza$$bDpto.
