摘要

Pure phase Fe doped BaTiO3 crystals have been successfully fabricated at 200°C with 0.7M KOH by a hydrothermal method.The obtained products were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM).An obvious morphology evolution from hexagonal shape to sphericity was observed when Fe doping concentration was increased from 0% to 1%,3%,6%,and 10%.In addition,the size of the obtained Fe doped BaTiO3 crystals obviously became smaller.The possible mechanism was also discussed.
