Resumo
Lanthanum chromite (LaCrO3) is one of the most adequate material for use as
interconnector in solid oxide fuel cell (SOFC) applications, due to its intrinsic properties,
namely its good electrical conductivity and resistance to environment conditions in fuel cell
operations. Due to difficulties in sintering, additives are usually added to help in the
densification process. In this work, the influence of added cobalt and strontium, in the
sintering of LaCrO3 obtained by combustion synthesis was studied. The starting materials
were respectively nitrates of chromium, lanthanum, cobalt and strontium, and urea was used
as fuel. The results show that by increasing the strontium and cobalt concentrations it is
possible to reduce the temperature of sintering. Using both additives, the sintering processes
took place in lesser times than normally used for this material, as well as greater values of
density were attained.
