| Summary: | © 2015 Elsevier Ltd. All rights reserved. In this work, properties of Ba(Zr 0.05 Ti 0.95 ) 1 - x (Fe 0.5 Ta 0.5 ) x O 3 ceramics with 0.00x 0.07 were investigated. The ceramics were fabricated by a solid state reaction technique. X-ray diffraction analysis indicated that all samples exhibited single phase perovskite. Examination of the dielectric spectra revealed that the Fe and Ta additives promoted a diffuse phase transition, and the two phase transition temperatures, as observed in the dielectric curve of pure Ba(Zr 0.05 Ti 0.95 )O 3 , merged into a single phase transition temperature for higher x concentrations. The transformation was confirmed by ferroelectric measurements. In addition, the doped ceramics exhibited high relative dielectric tunability, especially for higher x concentration samples. |
