Crystal structure modeling, electrical and microstructural characterization of manganese doped barium zirconium titanate ceramics

► The manganese substituted barium zirconium titanates are nano structured ideal perovskite phases having no distortion of TiO6/ZrO6/MnO6 octahedral chains. ► Rietveld refinement of MnBTZ samples converges to a satisfactory structure fit. ► Composition, temperature and frequency dependant dielectric behavior of the materials have been observed.
