BaTiO3 devices doped with Zr using mechanical alloying Article uri icon

abstract

  • The purpose of this work was to compare the microstructure and electrical characteristics of BaTiO3 devices doped with Zr for conventional fabrication and for mechanical alloying (MA). The sintered samples fabricated with MA powder showed better ZrO2 dissolution and smaller grain sizes than the conventional samples. Lower values of loss factor and higher resistivities were observed in devices fabricated with MA powders. When the ZrO2 concentration increases, the resistivity and the loss factor increase while the dielectric constant decreases. These effects are explained in terms of grain size reduction and lattice distortion. © 2006 Elsevier B.V. All rights reserved.
