Influence of nanogold additives on phase formation, microstructure and dielectric properties of perovskite BaTiO<inf>3</inf>ceramics

© 2015, Springer-Verlag Berlin Heidelberg. The formation of perovskite phase, microstructure and dielectric properties of nanogold-modified barium titanate (BaTiO3) ceramics was examined as a function of gold nanoparticle contents by employing a combination of X-ray diffraction, scanning electron mi...
