Effects of Bi2O3 and Cr2Ti3O9 Co-doping on dielectric properties in BaTiO3-based ceramics

► 0.98BaTiO3-0.01Cr2Ti3O9-0.01Bi2O3 ceramics exhibited a high dielectric propertie. ► The peaks of dielectric constants become broaden with increasing of doping concentration. ► Nonferroelectric phase BaCrO3 caused the diffusion phase transition.
