Chemical heterogeneity and approaches to its control in BiFeO3–BaTiO3 lead-free ferroelectrics

1 mol% MnO2 was used to improve electrical resistivity of lead-free 0.75BiFeO3–0.25BaTiO3 (75BFBT) ferroelectric ceramics; the materials were perovskite structured with major rhombohedral (R3c) phase. The method of incorporation of MnO2 was found to exert a significant influence on the structure, mi...
