Dielectric; diffuse phase transition; doped barium titanate

Ceramic samples of Li_0·1Ba_0·95(V_xTi_1−x)O₃, wherex=0 to 0·2 were prepared by solid state reaction method. The samples were characterized by XRD. The dielectric measurements have been carried out on the sintered disks as a function of the frequency (100 Hz-1 MHz) and temperature (300–420 K). The variation of dielectric constant with temperature indicates a diffuse phase transition in all the samples studied.
