biostudies-literatureUnknown10(1)Wu CCStrontium bismuth tantalate vanadate [SrBi₂(Ta_2-xV_x)O₉, SBTV] ceramics, which are bismuth-layered perovskite ferroelectrics, were synthesized through the solid-state reaction method. The effects of different sintering temperatures and V₂O₅ contents on the structure of the microstructure, Raman spectrum, and dielectric properties of the SBTV ceramics were investigated. As sintered at high temperature (980-1040 °C) and different V₂O₅ contents (x = 0.1 - x = 0.4), only disk-like grains of the SBTV ceramics were observed in the scanning electron micrographs. Preferential orientation of the crystals of the SBTV ceramics was confirmed through X-ray diffraction studies.
