Properties of La2-xSrxMo2-yWyO9-δ (x = 0-0.2, y = 0-0.3) synthesized via citrate gel method have been investigated on phase, oxidation state, microstructure and electrical conductivity. The XRD results show a single phase after calcination at 700 oC for all compositions. The oxidation state of Mo in La2-xSrxMo2-yWyO9-δ compositions determined by X-ray Absorption Near Edge Structure (XANES) is found to be +6. The average grain size of sintered compositions increases with the amount of Sr but slightly decreases with an addition of W. At 500 oC, all doped compositions exhibit higher conductivity as compared to 5.42×10-4 S∙cm-1 for undoped-La2Mo2O9. In this work, the composition of La1.9Sr0.1Mo2O9-δ performs the highest conductivity value of 1.95×10-3 S∙cm-1.
