Perovskite oxide powders of Co-doped lanthanum chromite were synthesized by dispersing precursor metal salt solutions in a polymer matrix followed by a thermal treatment. XRD patterns showed that a highly crystalline cobalt-doped lanthanum chromite was obtained. Fine perovskite powder with a surface area of 6.15 m2 g -1 calcined at 700oC for 1 h, were obtained. After the sample sintered at 1450oC for 3h, the powder reached high densities exceeding 97% of the theoretical density. The proposed here has proved to be a very promising technique for the synthesis of lanthanum chromite powders.971-976openAccesssynthesissinteringcobaltdoped materialslanthanum oxideschromium oxidespowderssolid oxide fuel cellsArtigo de periódico660-66110.4028/www.scientific.net/MSF.660-661.971https://orcid.org/0000-0002-0155-9100
