Preparation and electrical properties of (1 − x)Ba(Fe0.5Nb0.5)O3–xBaTiO3 ceramics

(1 − x)Ba(Fe0.5Nb0.5)O3–xBaTiO3 ceramics with giant dielectric constants and low losses were prepared by the conventional solid-state method. The phase structure, microstructures, electrical properties of the ceramics were investigated. The results show that the ceramics are of monoclinic structure and possess dense and fine microstructures. The incorporation of BaTiO3 can significantly reduce the dielectric loss and improve the frequency and temperature stability of the electrical properties of Ba(Fe0.5Nb0.5)O3.
