Temperature stability, structural evolution and dielectric properties of BaTiO3–Bi(Mg2/3Ta1/3)O3 perovskite ceramics

Lead-free (1−x)BaTiO3−xBi(Mg2/3Ta1/3)O3 [(1−x)BT−xBMT, 0≤x≤0.1] perovskite solid solutions were synthesized via the conventional solid state reaction technique. Raman spectra and XRD analysis demonstrate that a systematically structural evolution from a tetragonal to pseudo-cubic phase occurred near 0.01
