Synthesis of plate-like B-site complex perovskite Ba(Zr0.1Ti0.9)O3 microcrystals

摘要： B-site complex perovskite Ba(Zr0.1Ti0.9)O3 microcrystals at micron size with a plate-like shape was successfully synthesized using topochemical microcrystal conversion and molten salt method. A plate-like Bi4(Zr0.1Ti0.9)3O12 precursor was first synthesized by Zr4+ substitution of Ti4+ using molten salt. Then plate-like 4–9 μm Ba(Zr0.1Ti0.9)O3 microcrystals with an average thickness <500 nm were synthesized by mixing BaCO3, Bi4(Zr0.1Ti0.9)3O12, and KCl molten salt at 800 °C. Finally, the topochemical microcrystal conversion reaction between BaCO3 and Bi4(Zr0.1Ti0.9)3O12 precursor was carried out. The results pave the way for fabricating plate-like B-site complex perovskite microcrystals.
