Abstract

Ba₅NdTi₃V₇O₃₀ is a tungsten bronze structured ceramic sample, prepared by Solid State reaction route at high temperature (950℃). The room temperature XRD analysis confirms orthorhombic crystal structure of the compound. Dielectric peak is observed at ~460℃ showing the transition of the compound from ferroelectric to paraelectric phase. Appearance of hysteresis loop confirms the existence of ferroelectric properties in the materials. Different values of activation energy in different temperature regions of the ac conductivity versus inverse absolute temperature graph exhibit mixed type of conduction process in the compound (i.e., ionic-polaronic and space charge generated from the oxygen ion vacancies).
