Effect of vanadium doping on property of Bi4Ti3O12 fabrication and ceramics

Vanadium-doped bismuth titanate ceramics of composition Bi4Ti3-xVxO12+x/2 (BTV, x = 0.02, 0.03, 0.04, 0.06, 0.08) were prepared using the conventional solid-state reaction method. The sintering activity was significantly improved by the addition of even a small amount of vanadium. The effects of the incorporation of vanadium in the Bi4TiO12 lattice on the microstructure, Raman characteristics, dielectric and ferroelectric properties of the samples were investigated.
