Abstract

Nanoscale BaTiO3 powders were prepared by hydrothermal synthesis a mixture of H2O and EtOH was used as solvent and the phase distribution of the powders was investigated in terms of the ratio R of DI water H2O/H2O+EtOH The size of the powders was varied in the range of 20∼100 nm depending on the solvent condition Xray diffraction and Raman spectroscopy were applied to investigate the variation in the relative volume fraction of the tetragonal phase most of the powders contain both tetragonal and cubic phases The results obtained by the two different analysis methods appear to be very close to each other and it was found that the maximum volume fraction of the tetragonal phase was 23∼26 when the synthesis was performed at R = 025∼05
