Self-assembly growth of flower-like BiFeO3 powders at low temperature

In this work, flower-like BiFeO 3 powders were synthesized by a hydrothermal method at low temperature. The effects of mineralizer, reaction temperature and soak time on the crystal phase structure and morphology of the BiFeO 3 powders have been investigated. Perovskite BiFeO 3 powders were obtained as the concentration of KOH is 1–6 mol/L. The SEM images of BiFeO 3 powders which synthesized at 150 °C for 1 h with 2 mol/L KOH exhibit cubic morphology. Whereas, the powders prepared for 6 h show flower-like morphology.
