The structural, thermal and electrical attributes of co-doped SrTiO 3 system (La 3+ at Sr-site and Mo 6+ at Ti-site) were studied. The solid solution limit of La in SrTiO 3 and Mo in La 0.3 Sr 0.7 Mo x Ti 1-x O 3-δ was around 30 mol percent and 5 mol percent, respectively. Mo-doping in La 0.3 Sr 0.7 TiO 3-δ at 1000 °C resulted in improved crystallinity. The impure phase of Pyrochlore (La 2 Ti 2 O 7 ) and MoO 3 were resulted at a doping concentration of x ≥ 0.05. As a result, the amount of Mo increases, the structural changes are observed. The electrical conductivity of codoped La 0.3 Sr 0.7 Mo 0.05 Ti 0.95 O 3-δ was found to be 7.3 × 10 -5 S.cm −1 at 700 °C in air, indicating its potential as an anode candidate for applications in solid oxide fuel cell (SOFC).
