Solid‐State Synthesis of Nanocrystalline BaTiO3: Reaction ...

Abstract. The formation of BaTiO 3 nanoparticles by a solid-state reaction between nanocrystalline raw materials BaCO 3 and TiO 2 was studied as a function of temperature (400°–800°C), time (1–24 h), and titania particle size (15 and 30 nm). The reaction starts at 500°C and a high reaction rate is already observed at 600°C for the finest titania, with up to 90% conversion after 2 h.
