Abstract

Barium titanate (BaTiO₃) nanoparticles were successfully synthesized by using a surfactant-assisted method. The various processing parameters, namely, th e species of surfactant, reaction temperature and micro-emusion concentration had been varied, and the effects on the micrographs and crystal structure of BaTiO₃ particles had been analyzed by scanning electron microscope (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD). XRD analyses confirming the tetragonal structure of the BaTiO₃ nanoparticles using hexadecyl trimethyl ammonium Bromide (CTAB) or nonylphenol polyoxyethylene ether (NP-10) as surfactant. The SEM analysis showed that by changing the species of surfactant, grains with different dimensions could be synthesized. TEM analyses indicate that BaTiO₃ nanoparticles with 15–20 nm in diameter were successfully synthesized.
