Synthesis of MTiO3 (M = Ba, Sr) Nanoparticles in n-butylamine by Following a Solvothermal Route

Barium titanate (BaTiO3) and strontium titanate (SrTiO3) nanoparticles are prepared in n-butylamine by following a solvothermal route. The as-prepared BaTiO3 and SrTiO3 nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and high resolution transmission electron microscopy (HR-TEM). The results indicate that the as-prepared BaTiO3 are about 20 nm in diameter and SrTiO3 nanoparticles are about 16 nm in diameter. The formation mechanism finally was discussed, and the preliminary results suggest that this synthesis procedure could be developed to a general strategy for the preparation of other perovskite nanoparticles.
