Synthesis and Structural Characterization of Nanoscale BaTiO3 Powders
Nanoscale BaTiO3 powders were prepared by hydro-thermal synthesis as a function of solvent conditions. The size of the BaTiO3 powders was in the range of 20 ~ 100 nm. The variation in the relative volume fraction of the tetragonal phase was analyzed quantitatively by means of XRD and Raman spectroscopy. It was found that the maximum volume fraction of the tetragonal phase was ~ 29 %; this was obtained when the synthesis was performed at a solvent condition R (H2O/(H2O + EtOH)) = 0.25.
