Abstract: According to modern researchers ferroelectric ceramics show good insulating behaviour and are widely used as base materials for composite film and high frequency resistors. So it requires a meticulous analysis of transport properties of these materials. Sr5NdTi3V7O30 is a lead free Tungsten Bronze ceramic prepared by high temperature solid state reaction route. Room temperature XRD study confirms single-phase orthorhombic structures The SEM study of the sample showed no structural variation, non-uniformly distributed grain. Dielectric study reveals that there is no phase transition within the observed experimental temperature range. But presence of hysteresis loop confirms the ferroelectric nature of the sample. Various conduction mechanisms are observed in ferroelectrics. In this paper emphasis is given on the study of dielectric and electrical conductivity. The frequency dependent a.c. conductivity obeys the Jonscher’s power law. The nature of variation of dc conductivity with temperature suggests Arrhenius type of electrical conductivity.
