Pure and Bi-doped samples of SrTiO: with Sr/Ti ratios ranging from 0.980 to 1.010 were sintered in air at 1500 Β°C. Grain growth was promoted in the non-stoichiometric bismuth-doped compositions. Unlike the non-doped samples which were ohmic insulators, bismuth-containing specimens showed non-ohmic b
