Abstract
ac impedance spectroscopy studies were carried out in polycrystalline samples of Li2Zr1-xTixO3:0 < x < 0.3, solid solutions. These materials present mixed ionic and electronic conductivity: sigma=1X10(-6) (Omeg a cm)(-1) at 400 degrees C rising to sigma=1X10(-3) (Omega cm)(-1) at 750 degrees C. It was found that the conductivity and the E(a) values decrease with increasing Ti4+ content. The dielectric constant decreas es sharply with increasing Ti content. Using the same ac data the hopp ing rate characteristics and de component were investigated.
