A method for synthesis of high aspect ratio platelet seeds by growth of SrTiO 3 on Sr 3 Ti 2 O 7 core particles is reported. The aim of this study was to identify and control the morphology and size of SrTiO 3 particles via molten salt synthesis. Platelet and tabular morphologies with rectangular faces were obtained using rutile and anatase, respectively. Platelet SrTiO 3 particles with an edge length of 10–40 μm and a thickness of 1–4 μm were obtained. High aspect ratios (edge length to thickness) of 7–10 were measured for platelet particles as opposed to lower aspect ratios of 2–4 for tabular particles. Highly anisotropic platelets are suitable template candidates to achieve textured ceramics.
