Synthesis of single-crystal Ba1−xSrxTiO3 (x = 0–1) dendrites via a simple hydrothermal method

In this paper, we report a simple hydrothermal method to synthesize barium strontium titanate (Ba1−xSrxTiO3, x = 0–1) dendrites without any templates. The obtained products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), electron diffraction (ED), and energy-dispersive X-ray spectroscopy (EDX), respectively. All the samples were identified as cubic perovskite phase by XRD and the obtained Ba1−xSrxTiO3 (x = 0–1) dendrites were single-crystal. The formation process of Ba1−xSrxTiO3 dendritic structures was also investigated. It is rational to expect that dendritic structures of other perovskite oxides may also be synthesized by this simple method.
