Effect of Ba-Ions on The Structural Properties of The [(Pbxba1-X)0.81La0.125]Tio3Ceramic

Abstract

Abstract. Eight samples were prepared according to the concentration of Ba-content (0, 10, 20, 30, 40, 55, 60 and 70 %). In the present research, full structural Investigations for of the [(PbxBa1-x) 0.81La0.125] TiO3ceramic compounds were accomplished using x-ray diffraction technique. The results extracted includes: the lattice parameters, the grain size and the percentage of crystallinity % of the compound. The investigation of the structural properties of this compound is useful for studying the dielectric and related properties such as the piezoelectric applications. Among the unique results found in the present investigation, we found that above 40 % of Ba, the compound is no longer tetragonal but it is converted into the cubic system (structural transformation).
