High purity BaTiO 3 nanopowders were pressed into pellets and annealed between 100 and 1200°C. The crystal quality and grain size of the BaTiO 3 nanocrystals were characterized by X-ray diffraction measurements. Annealing induces an increase in the grain size from 44 to 82nm with temperature increasing up to 1200°C. XRD and Raman spectroscopy studies confirm that all the samples were...
