Resumo
Doped lanthanum chromite is a promising as interconnect material because of its good
conductivity at high temperatures and its stability in oxidizing and reducing atmospheres. 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.
