Abstract

Polycrystalline Samples of Ba5RTi3V7O30 (R= Pr, Tb), members of tungsten bronze  family were prepared by high temperature Solid State Reaction Technique.  Preliminary X-ray analysis of the material has been done to ensure the single phase  formation. Surface morphology was studied by Scanning electron microscope (SEM:  JOEL-IT300). Dielectric characterization is done for frequency upto 1MHz at various  temperatures by Impedance Analyser (HIOKI-IM3536).
