Abstract
Ba(Zr0.10Ti0.90)O3 (BZT) and V substituted BZT ceramics (BZT:V) were prepared by mixed oxide method and polymeric precursor method. The effect of V5+ addition in the BZT lattice was evaluated by X-ray diffraction (XRD) and Fourier transform Raman (FT-Raman) spectroscopy. When vanadium is introduced in the BZT lattice there is a decrease in the grain size. Substitution of vanadium on B-site broads the dielectric permittivity curve. That can be caused by repulsion of vanadium with their next nearest neighbors leading to a structure which is tetragonally distorted.
