Abstract

Effect of glass addition (0.5, 1, 1.5, 2 wt%) on the dielectric, ferroelectric and energy storage properties of barium titanate (BT) ceramic was studied. Phase formation was confirmed by XRD. Lattice parameters were determined by Rietveld refinement and crystallite size, microstrain was determined by W-H plots. Relative density was found to be increasing with addition of glass. Glass addition reduces the dielectric constant of pure BT and maximum value of dielectric constant was found to be 1469 at 1 kHz for 1.5 wt% glass addition. Highest energy efficiency is obtained for 1 wt% glass added BT sample.
