Description An oxide ion conducting material, La1.94Ba0.06Mo2O9, with ionic conductivity of the order of 0.084 S/cm at 800 degreesC in air was prepared by a citrate-nitrate auto-ignition process. A 3% Ba doping has suppressed the resistive transition of unsubstituted La2Mo2O9, which in turn stabilized the high-temperature cubic phase at room temperature as confirmed from x-ray diffraction, differential thermal analysis, and dilatometric studies. Impedance measurements on sintered La1.94Ba0.06Mo2O9 further lend strong support that a small amount of Ba doping has increased the overall conductivity of the parent compound La2Mo2O9 to a notable extent both at low and high temperatures.
