In this study, 0.75BiFeO3-0.25BaTiO3 ceramics doped with Mn and Cu (0, 1, 2, 3, 4 and 5 mol%) have been fabricated with an effective solid-state reaction method developed for high purity ceramics. Attention has been focused on relationships between phase formation, density,dielectric and ferroelectric properties of the sintered ceramics. It was found that Mn and Cu doping affected the dielectric and ferroelectric properties of these ceramics. In addition, Cu and Mn doping was also found to improve the sintering ability and change the structural symmetry of this system from rhombohedral to tetragonal.
