Abstract

Abstract The effect of vanadium doping on the structural, dielectric and ferroelectric properties of Bi4Ti3O12 (BTO) has been studied. Bi4–x/3Ti3–xVxO12 (x = 0, 0.006, 0.012, 0.018, 0.024 and 0.03 mol%) were prepared using a sol–gel synthesis method and calcined at 400 °C for 3 h. All samples were sintered at 950 °C for 3 h. The relative density of ceramic samples decreases with the addition of vanadium. The structural analysis confirms that no structural changes occur with doping of vanadium into BTO ceramics. Doping of vanadium into BTO ceramics improves its ferroelectric and dielectric properties.
