EFFECT OF THE CALCINATION TEMPERATURE ON THE DIELECTRIC PROPERTIES OF 0.94NA0.5BI0.5TIO3–0.06BATIO3 CERAMICS
Abstract
With the miniaturization of electronic products, the portability and the critical need of clean energy for environment have led to the development of lead-free electroceramics. In this work, lead-free dielectric ceramics of 0.94Na0.5Bi0.5TiO3–0.06BaTiO3 (NBT–0.06BT) are synthesized by wet solid-phase method. The effects of calcination temperature on phase structure, morphology, densification behavior and dielectric properties are investigated. The XRD results indicate that all samples demonstrate typical diffraction peaks of perovskite structure. The SEM and dielectric analytical results show that high-performance dielectric property of NBT–0.06BT ceramic with dense microstructure and appropriate grain size can be achieved when the calcination temperature is appropriate.
