Strontium- and Li-doped-lanthanum orthogallate, (La0.9Sr0.1Ga1−yLiyO3−δ; y = 0.05 and 0.10), were synthesized via soft-chemistry route of metal nitrate–glycine combustion. Systematic phase and microstructural evolution as a function of

processing temperature was followed by X-ray diffraction and scanning electron microscopy of the calcined and sintered samples. Electrical characterization on the sintered sample by the 4-point DC and AC impedance measurements at 550 to 850C showed that Li-doping at B-site in LaGaO3 yielded a conductivity which was higher than that of yttria-stabilized zirconia, but somewhat inferior to the Mg-doped analogues.
