Wet-Chemical Synthesis and Characterization of Surface-Modified Barium Titanate Nanocomposites

Abstract

Abstract: The wet-chemical preparation of barium titanate nanocomposites surface-coated with stearate was described. The chemical binding between stearate and metallic cations can be confirmed from both FT-IR and XPS results. Although amorphous BaTiO3 obtained, tetragonal phase of nuclei can be inferred from both XRD and Raman patterns. The particles size is around at 10-20nm determined by TEM morphology. The nucleation and epitaxial growth of crystalline are significantly effected in the presence of organic modifying groups.

Key words: barium titanate, nanoparticles, surface-modification, epitaxy
