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).
