N2 - BaTiO3 powders was synthesized from cheap and readily available H2TiO3 and Ba(OH)2 by solid-state reaction at low temperature. The samples were characterized by thermogravimetry and differential scanning calorimetry (TG-DSC), X-ray diffraction (XRD), Scanning electron microscope (SEM), Raman spectroscopy, Fourier-Transform Infrared Spectroscopy (FTIR). The results show that the pure cubic BaTiO3 powders with an average size of about 68 nm was prepared at 600℃ for 4 h and Monodisperse tetragonal (c/a = 1.0100) BaTiO3 powder with an average size of about 242 nm was prepared by calcination at 900℃ for 4 h, suggesting its promising applications in multilayer ceramic capacitors (MLCC). Compared with BaCO3 and TiO2 as raw materials, Due to the low decomposition temperature of Ba(OH)2 and the small particle size of H2TiO3, the synthesis temperature of pure BaTiO3 decreased by 200℃, and the phase transition temperature decreased by 100℃. The method can be used to synthesize functional ceramic powders with different crystal phase levels.
