The dopant strontium increases the electronic conductivity of the material, besides presents an excellent electrochemical performance, relatively good chemical and thermal stability and compatibility with solid electrolyte of ZrO2/Y2O3 (YSZ). In this work, a contribution to the study of synthesis of LSM is presented with strontium concentration of 50 mol % by the citrate technique. The powders have been characterized for various techniques, as gas absorption and adsorption, X-ray fluorescence spectroscopy, laser scattering granulometry, gas helium picnometry, scanning electron microscopy (SEM), X-ray diffractometry (XRD) and calculations of theoretical density and particle average diameter. The ceramics have been characterized by SEM and XRD. The adequate characteristics of LSM have been evaluated aiming at the use in the preparation of suspensions for cathodic thin films of SOFCs.Artigo IPEN-doc 12300 Catodo para celula a combustivel de oxido solido: Sintese e caracterizacao de manganito de lantanio dopado com estroncio2007 - CHIBA, R.; VARGAS, R.A.; ANDREOLI, M.; SEO, E.S.M.Artigo IPEN-doc 13140 Deposition of strontium-doped lanthanum manganite suspensions by Wet Powder Spraying2008 - CHIBA, RUBENS; VARGAS, REINALDO A.; ANDREOLI, MARCO; SEO, EMILIA S.M.Artigo IPEN-doc 15711 Strontium dopant concentrations influence on Ndsub(1-x)Srsub(2)MnOsub(3+'gamma') structural and electrical conductivity2010 - VARGAS, REINALDO A.; CHIBA, RUBENS; ANDREOLI, MARCO; SANTORO, THAIS A. de B.; SEO, EMILIA S.M.Artigo IPEN-doc 15712 Crystalline structure and microstructural characteristics of the cathode/electrolyte solid oxide half-cells2010 - CHIBA, RUBENS; VARGAS, REINALDO A.; ANDREOLI, MARCO; SANTORO, THAIS A. de B.; SEO, EMILIA S.M.Artigo IPEN-doc 15715 Strontium-doped neodymium manganite powders obtained by the solids mixture technique2010 - VARGAS, REINALDO A.; CHIBA, RUBENS; ANDREOLI, MARCO; SEO, EMILIA S.M.Artigo IPEN-doc 18277 Forming of cathodic ceramic film using airbrush for application in high temperature solid oxide fuel cells2012 - CHIBA, RUBENS; VARGAS, REINALDO A.; ANDREOLI, MARCO; SEO, EMILIA S.M.
