  • Solid‐State Synthesis of Nanocrystalline BaTiO3: Reaction

    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.

    5/26/2005· Barium titanate has been prepared by solid‐state reaction of nanocrystalline TiO 2 (70 nm) with BaCO 3 of different particle size (650, 140, and 50 nm). The results give evidence of a strong effect of the size of BaCO 3 in the solid‐state synthesis of barium titanate. The use of nanocrystalline BaCO 3 already leads to formation of the single‐phase BaTiO 3 after calcination for 8 h at 800°C.
