xBaZr0.2Ti0.8O3-(1-x)BiFeO3(x=0, 0.3, 0.5, 0.7) solid solution ceramics were prepared by conventional solid-state reaction method. The crystal structure and dielectric properties ofxBaZr0.2Ti0.8O3-(1-x)BiFeO3ceramics have been investigated. The result indicates that the crystal structure of solid solution ceramics changes from rhobohedral to pseudocubic structure with the increase of barium zirconate titanate content. The room temperature dielectric constant of all samples decreases with the increasing of frequency. When the temperature is in the range of 30oC~150oC, the dielectric constant of all samples increases as temperature rises. In the same temperature range, the dielectric loss of BiFeO3ceramics increases with the rise of temperature and the dielectric loss ofxBaZr0.2Ti0.8O3-(1-x)BiFeO3(x=0.3~0.7) changes a little. The addition of barium zirconate titanate leads to the decrease of dielectric loss and leakage current for BiFeO3ceramics.

Barium zirconate titanate, BaZrxTi1-xO3, (BZT) with x compositions have been widely studied as a potential candidate for antenna application. In this study, BZT film was prepared using the electrophoretic deposition (EPD) method. The EPD method was used to produce BZT composite into film for miniaturization purposes and dielectric properties improvement. The EPD process was performed with varying pH, voltages, deposition time and amount of Zr. The results showed that optimum deposition time was obtained at pH 4, 90V and 1 minute deposition time. Increasing Zr content decreased the dielectric constant of the BZT composite, and increased the loss tangent of the samples. The result is in agreement with microstructure observation that Zr addition in BZT decreased the grain size that suppressed the dielectric properties. This makes BZT is a suitable candidate for antenna application.
