So all researches on the direction to clarify some aspects of this material continue to be an interesting contribution to understand and modify the behavior of the Lanthanum Chromite in use. The effort of this work is attaining doped Lanthanum Chromite by combustion synthesis, optimizing the parameters of the synthesis process and studying the influence of the conditioning powder process as milling, atmosphere and temperature of the sintering and also additives concentration on the final density, crystalline structures and expansion thermal behavior. The main characterization techniques used were BET determinations, Archimedes density method, dilatometry, scanning electronic microscopy, X ray diffraction and Rietveld method for refinements of the phases quantification. The homogeneous Lanthanum Chromite doped with Strontium and Cobalt with sintered densities around 97th% and thermal expansion coefficient compatible for SOFC applications (12x10-6°C) were attained with control of the adequate concentrations additives, synthesis conditions, the control of the atmosphere, time and temperature of the sintering process.Capítulo IPEN-doc 14158 Phase segregation of (Hg, Re)-1223 superconductor2005 - MARTINEZ, L.G.; CORREA, H.P.S.; FERREIRA, F.F.; GARCIA, F.; TAMURA, E.; PASSAMAI JUNIOR, J.L.; PASSOS, C.A.C.; ORLANDO, M.T.D.; MELO, F.C.L.Capítulo IPEN-doc 14401 Strutural study of lanthanum oxysulfate (LaO)sub(2)SOsub(4)2007 - ORLANDO, M.T.D.; CORREA, H.P.S.; MARTINEZ, L.G.Resumo IPEN-doc 13836 The influence of external pressure on the intrinsic term in Hg, Re-1223 superconductor2008 - ORLANDO, M.T.D.; GARCIA, F.; CARVALHO, E.J.; AZEVEDO, G. de M.; MARTINEZ, L.G.; CORREA, H.P.S.; PASSOS, C.A.C.; PASSAMAI JUNIOR, J.L.; ROSSI, J.L.Resumo IPEN-doc 14446 A papillary CaCsub(2)Osub(4):Hsub(2)O stone: A study on the core composition from XPD by Rietveld Method2007 - KUPLICH, L.; SOUZA, D.O. de; DEPIANTI, J.B.; MEDEIROS, E.F.; ORLANDO, M.T.D.; MARTINEZ, L.G.; CORREA, H.P.S.; ORTIZ, R.P.; COLATTO, L.P.Resumo IPEN-doc 14448 Evaluation of precursor on the Hg,Re-1223 polycrystalline samples2007 - PASSAMAI JUNIOR, JOSE L.; PASSOS, CARLOS A.C.; CRUZ, PAULO C.M. da; ORLANDO, MARCOS T.D.; PINHEIRO, CINTIA G.; CORREA, H.P.S.; MARTINEZ, L.G.Resumo IPEN-doc 14449 X-ray diffraction and electrical resistivity analysis on granular on (Hg,Re) - 1223 superconductors2007 - PASSOS, C.A.C.; ORLANDO, M.T.D.; PASSAMAI JUNIOR, J.L.; CRUZ, P.C.M.; MELLO, E.V.L.; CORREA, H.P.S.; MARTINEZ, L.G.Resumo IPEN-doc 16707 Estudo da cristalinidade de amostras de polipropileno isotáctico por difração de raios X e microscopia eletrônica de transmissão2009 - LIMA, L.F.C.P.; OLIANI, W.L.; OTAGURO, H.; PARRA, D.F.; LUGAO, A.B.; OLIVEIRA, R.R.; CORREA, H.P.S.; ORLANDO, M.T.D.; MARTINEZ, L.G.
