Investigation of structural and electrical properties of (1 − x) Bi0.5Mg0.5TiO3–(x) PbTiO3 ceramic system
چکیده انگلیسی

[(BiMg0.5Ti0.5O3)1−x][PbTiO3]x (BMT–PT) ceramic powders of different compositions were prepared by solid-state reaction method. X-ray diffraction analysis of the compounds suggest the structural change (rhombohedral to tetragonal) in these ceramics. SEM photographs exhibit the uniform distribution of grains with less porosity. Polarization vs. electric field (P–E) studies show maximum remanent polarization (Pr ∼ 7.9 μC/cm2) for composition x = 0.34. The dielectric peaks were found to be broadened that indicates the existence of diffuse phase transition. Diffusivity (γ) study of phase transition in these compounds provided values between 1 and 2 indicating the variation of degree of disorderness in the system.
