The evolution of phase and defect structure in BaTiO3 nanopowders synthesized by an alkoxide–hydroxide process in benzyl alcohol under reflux conditions were investigated. As-prepared powders were heat-processed at temperatures ranging from 250 to 850°C. X-ray powder diffraction (XRD) showed that Ba...
