Impedance spectroscopy and dielectric properties of BaAl(2−2x)(Zn0.5Ti0.5)2xO4 ceramics
Source abstract
Abstract
Abstract The current study investigated the dielectric and electrical properties of BaAl(2−2x)(Zn0.5Ti0.5)2xO4 ceramics, with x = 0, 0.4%, 0.8%, 1.2% and 1.6%, via impedance spectroscopy. The co-doping of Zn and Ti improved the temperature stability over −100 °C–700 °C of er and lowered tanδ due to the electron-pinned defect-dipoles. Effects of oxygen partial pressure on the electrical, dielectric and ferroelectric properties of x = 1.6% ceramic were studied as well. The bulk conductivity of the N2–H2-sintered and O2-sintered samples was attributed to the e ' and h • , respectively.
