A novel solvothermal route has been developed to synthesize highly dispersed nanocrystalline barium titanate (BaTiO 3 ), using a mixture of ethylenediamine and ethanolamine as a solvent. The as‐synthesized BaTiO 3 nanoparticles were characterized by X‐ray powder diffraction, transmission electron microscopy (TEM), high‐resolution TEM, Fourier transform infrared spectroscopy, and thermal analysis. Based on the results of characterizations, the organic solvent was found to influence strongly the crystal growth and dispersibility of BaTiO 3 . The BaTiO 3 nanoparticles obtained were highly dispersed and crystalline with a cubic perovskite structure. The particle size derived from the TEM ranged from 5 to 20 nm.
