INFLUENCE OF VANADIUM DOPPING ON DIELECTRIC PROPERTIES OF BARIUM TITANATE CERAMICS
Languages of publication
The purpose of this article is to present the impact of vanadium substitution on the dielectric properties of barium titanate. Doping barium titanate (BaTiO3) by different ions such as vanadium V5+ provides the possibility of changing its dielectric properties. SEM images indicate the differences between pure BaTiO3 (BT) and Ba(Ti0.98V0.02)O3 (BTV2). Using dielectric measurements, the Curie temperatures (Tc) were calculated – they were found to be equal to 403 K and 396 K, respectively. Moreover, for BTV2 the Curie - Weiss temperature and the Curie constant (C) were determined (T0 = 368 K and C = 1.46 ×105 K, respectively).
