AbstractA novel method for synthesizing Na0.5Bi0.5TiO3 (BNT) anisotropic particles with grain orientation is reported. Anisotropically shaped particles of BNT were prepared by conversion of Na0.5Bi4.5Ti4O15 (NBT15) single crystals. Platelet NBT15 was produced by molten-salt synthesis. They were converted to BNT by second molten-salt synthesis at 800—1200 ?C. NBT15 single-crystal platelets were transformed into platelet particles of polycrystalline BNT. The reaction is topotaxial, those recrystallized BNT were oriented with (h 0 0) plane parallel to the platelet. The use of converted BNT particles as seed was confirmed by performing templated grain growth (TGG) of BNT with 5% grain-oriented, anisotropic particles of BNT. 相似文献
