XRD investigations have shown that the powders synthesized by hydrothermal reaction with or without ball milling were crystallized as cubicBaTiO 3 because the Xray diffraction peak at 2θ ∼45° (, (2 0 0) peak) is a single peak (Fig. 2 a).These patterns revealed that BaTiO 3 powders could be synthesized at 100 °C by hydrothermal reaction. In addition, the Ba/Ti ratio of the ...
