Effect of Sr and Al or Fe co-doping on the sinterability and conductivity of lanthanum silicateoxyapatite electrolytes for solid oxide fuel cells
The effect of co-doping of Sr and Al or Fe on the microstructure, sinterability and oxide-ion conductivity of lanthanum silicate oxyapatites is investigated in detail at 300–800 °C by the electrochemical impedance spectroscopy. The oxide-ion conductivity is 1.46 × 10−2 S cm−1 for La9.5Sr0.5Si5.5Fe0....
