A Ba<SUB>0.9</SUB>Bi<SUB>0.1</SUB>TiO₃ solid solution was prepared by substituting 0.1 mole % Bi₂O₃ at the Ba<SUP>2+</SUP> sites in BaTiO₃, and its dielectric properties were investigated. The Ba<SUB>0.9</SUB>Bi<SUB>0.1</SUB>TiO₃ solid solution was sintered at 1310 ℃ for 5 h. The stable formation of the perovskite structure was confirmed through X-ray diffraction, energy-dispersive X-ray spectroscopy, and field emission scanning electron microscopy. Unlike pure BaTiO₃, pyrochlore Bi₂Ti₂O<SUB>7</SUB> was observed in Ba<SUB>0.9</SUB>Bi<SUB>0.1</SUB>TiO₃ at approximately 27.1º. Overall, the perovskite structure was well formed. The Ba<SUB>0.9</SUB>Bi<SUB>0.1</SUB>TiO₃ solid solution showed typical dielectric properties and followed the modified Curie–Weiss law. In addition, the curve of the dielectric constant vs. temperature showed an extremely gradual change compared to the phase transition behavior of BaTiO₃.
