N2 - BaTiO3 nanoparticles were prepared for the first time employing a solvothermal process from the synthetic precursors of K2Ti6O13 nano-whiskers. The obtained samples were characterized by X-ray diffraction, transmission electron microscopy, selected area electron diffraction, and high-resolution transmission electron microscopy, etc. The results indicate that well-crystallized single-phase BaTiO3 nanoparticles are synthesized using K2Ti6O13 as precursors under solvothermal conditions at as low as 0.9 M. The solvothermal method facilitates the crystallinity and formation of the BaTiO3 nanoparticles. However, the K+ ions cannot be completely replaced by Ba2+ by the hydrothermal method even at 10 M due to its unique and extremely stable "tunnel" structure. The solvothermal method provides new avenues for the ion-exchange synthesis of a variety of other perovskite-type materials such as MTiO3 (M = Pb, Sr, Ca, etc.).
