(Bi0.5Na0.5)0.93Ba0.07TiO3 lead-free ceramics with addition of Ga2O3

As a candidate of a lead-free (Bi0.5Na0.5TiO3)0.93(BaTiO3)0.07+ x wt% Ga2O3 with x=0.0-0.2 has been synthesized by solid-state sintering ceramic-fabrication technique. The effect of Ga2O3 addition with ceramics enhanced the dielectric constant of free (Bi0.5Na0.5TiO3)0.93(BaTiO3)0.07+ x wt% Ga2O3 ceramics significantly. At room temperature, the dielectric constant is increased and relatively low dielectric loss occurred at high frequencies. X-ray diffraction pattern showed that the coexistence of tetragonal and rhombohedral phases in the (Bi0.5Na0.5TiO3)0.93(BaTiO3)0.07 composition was not changed by adding Ga2O3
