Abstract: Lead-free perovskite Ba(In(1/2)Nb(1/2))O(3) was prepared by conventional ceramic fabrication technique at 1350 degrees C/5 h in air atmosphere. The crystal symmetry, space group and unit cell dimensions were determined from Rietveld analysis using FullProf software whereas crystallite size and lattice strain were estimated from Williamson-Hall approach. XRD analysis of the compound indicated the formation of a single-phase cubic structure with the space group Pm3m. EDAX and SEM studies were carried out in order to evaluate the quality and purity of the compound. Complex impedance as well as electric modulus analyses suggested the dielectric relaxation to be of non-Debye type. The correlated barrier hopping (CBH) model was employed to successfully explain the mechanism of charge transport in Ba(In(1/2)Nb(1/2))O(3). (C) 2010 Elsevier B.V. All rights reserved.
