Abstract

Ru-doped lanthanum chromates (LaRuxCr1-xO3) were prepared through a solid-state reaction method. The perovskite pellets with high bulk density over 98% were obtained using the as-prepared LaRuxCr1-xO3 powders as starting materials by spark plasma sintering (SPS) process. The pellets performed high electrical conductivity, which increased with increasing of temperature and ruthenium content (0≤x≤0.10). The activation energy of lanthanum chromate was found to be decreased due to the ruthenium doping.
