Effect of BiMO3 (M=Al, In, Y, Sm, Nd, and La) doping on the dielectric properties of BaTiO3 ceramics

In this study, in order to enhance the energy storage density, 10% BiMO3 doping is performed in BaTiO3 ceramics (M=Al, In, Y, Sm, Nd, La) by a traditional solid-state method. The effects of different M3+ radii on the structural characteristics, dielectric properties, and energy storage are investigated systematically. The locations of the M-ions gradually shift from B-site substitutions to A-site substitutions with the increase in the ionic radius, which affect the structural characteristics and the dielectric properties.
