摘要
Ru-doped lanthanum chromates (LaRu x Cr 1− x O 3 ) were prepared through a solid-state reaction method. The perovskite pellets with high bulk density over 98% were obtained using the as-prepared LaRu x Cr 1− x O 3 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.
