摘要：
Monodispersed BaTiO3 nanoparticles with an average grain size of 3-5 nm were obtained by a convenient one-step solvothermal method. In this method, the crucial step to achieve ultrafine BaTiO3 nanoparticles is the control of hydrolysis of Ti(OC4H9)(4) by Diethylene glycol (DEG). DEG can strongly inhibit the hydrolysis procedure and prevent the grain growth of BaTiO3 nanoparticles. Ba(OH)(2)center dot 8H(2)O provides H2O source and alkaline environment. Polyvinyl pyrrolidone (PVP) is used as surfactant. The as-prepared monodispersed BaTiO3 nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), BET-specific surface area measurement, fouriertransform infrared (FT-IR) spectrum and X-ray photoelectron spectroscopy (XPS). The influence of concentration, temperature, time and the importance of PVP were explored to investigate the growth-up mechanism of the BaTiO3 nanoparticles. (C) 2013 The Ceramic Society of Japan.
