N2 - Indium and iron were co-doped at the Ti site of strontium titanate (SrTiO3) as dopant to improve the electrical properties of the anode material for solid oxide fuel cells. The effect of B-site deficiency on the weight loss, phase, lattice parameter, density, microstructure and electrical properties of Sr(Ti0.8In0.1Fe0.1)1−xO3−δ (x = 0, 0.02, 0.06) samples was investigated. A compound solid solution was formed at 977 °C. Sr(Ti0.8In0.1Fe0.1)1−xO3−δ powders sintered at 1435 °C for 5 h in air exhibited a single-phas cubic perovskite structure. With increasing B-site deficiency level, the relative density and sinterability of (In, Fe) co-doped SrTiO3 decrease, whereas its lattice parameter, porosity and total conductivity increase.
