The 90 nm grained Ce₀,₈Sm₀,₂O₁,₉ (SDC) ceramic with relative density of 97% was consolidated via SPS at 1050—1150 °C. The total conductivity values of 0,0079—0,0115 S/cm at 600 °C were obtained. A new approach to improve the grain-boundary conductivity of SDC nano-ceramic has been suggested. The app...
