Grain size and grain boundary misorientations of niobium-doped and undoped polycrystalline SrTiO3 have been investigated as a function of sintering time, in order to clarify conflicting reports about grain growth in this material. The observations suggest that the prevalence of both low angle grain boundaries and low energy CSLs are strongly correlated to both abnormal grain growth and sintering time. In addition, GB roughness as a function of sintering time has been investigated.
