英文摘要	A-site complex perovskite Ba1-xCaxTiO3 (x≤0.25) platelike particles with high aspect ratio (edge length to thickness) of 8-10 and micron sizes (6-8 μm) were synthesized via a topochemical microcrystal conversion reaction between the platelet Bi 4Ti3O12 and the powdered BaCO 3-CaCO3 mixture at 950 C in KCl flux. The morphology and A-site elemental composition of the resulting particles has been studied with reference to the effect of the concentration and molar ratio of the Ca 2+ and Ba2+ in molten salt. The A-site elemental composition of the resultant particles was correspond linearly to the molar ratio of the Ca2+ and Ba2+ in molten salt. The morphology and size distribution of the synthetic Ba1-xCaxTiO 3 particles was inherited from that of the precursor phase Bi 4Ti3O12. The designed synthesis routine has potential to synthesize other A-site complex perovskite platelike particles with high aspect ratio and micron sizes, which serving as a suitable template and seeded crystals can be employed to produce highly textured ceramics via TGG/RTGG method and single crystals by SPC technique. © 2013 Elsevier Ltd and Techna Group S.r.l.
